A full outer join keeps all rows of data from both the master and detail sources. This means that it includes all records from both tables, even if there is no match between the tables based on the join condition. It combines the results of both the left and right outer joins, ensuring that no data is left out.

The correct answer is "Normalizer". A normalizer is a transformation used in COBOL source to convert data from one format to another, typically by removing inconsistencies, redundancies, or anomalies in the data. It helps to standardize and organize the data in a consistent manner, making it easier to process and analyze.

"Run in six-month" is not a scheduling option to run a session because it does not specify a specific frequency or interval for the session to be run. The other options, such as "Run only on demand," "Run once," "Run every," and "Customized repeat," provide specific scheduling options for running a session either on-demand, once, at regular intervals, or with a customized repeat pattern.

The given expression uses the SUBSTR function to extract a substring from the string "Informatica". The starting position of the substring is determined by the result of the INSTR function, which finds the position of the first occurrence of the character "i" in the string "Informatica". Since the starting position is 1, the substring starts from the first character "i" and includes all the characters after it. Therefore, the output will be "informa".

A "confirm fact" is not a type of fact. In data warehousing, facts are the measurable and quantifiable data that represent business transactions or events. Semi-additive and additive facts are types of facts that can be aggregated, whereas "confirm fact" is not recognized as a valid type of fact in this context. "Not additive" is not a type of fact either, but it is not the correct answer in this case.

The Joiner transformation supports four types of joins: Full Outer, Master Outer, Normal, and Detail Outer. A Full Outer join returns all rows from both the master and detail sources, including unmatched rows. A Master Outer join returns all rows from the master source and only matching rows from the detail source. A Detail Outer join returns all rows from the detail source and only matching rows from the master source. Lastly, a Normal join returns only matching rows from both sources, excluding unmatched rows.

The correct answer is "By Using 'Lookup Policy on Multiple Match' option". This option allows you to define a policy on how to handle multiple matches in the lookup transformation. It provides you with the flexibility to choose whether to select the first match, select the last match, select all matches, or select none of the matches. This helps in handling situations where there are multiple possible matches for a lookup value in the reference table.

A master outer join is a type of join that keeps all rows of data from the detail source and includes matching rows from the master source. In other words, it ensures that all rows from the detail source are included in the result set, regardless of whether there is a match in the master source.

The property "re-cycle" is not a property in a sequence generator. The other options, "Start Value," "Current Value," and "Number of Cached Values," are all properties that can be associated with a sequence generator.

The correct answer is SETVARIABLE. This variable sets the current value of a mapping variable to a value specified by the user and returns that specified value. It allows the user to assign a specific value to a mapping variable, which can then be used in calculations or other operations within the program.

Type 1 SCD methodology overwrites old data with new data. This means that when a change occurs in a dimension attribute, the old data is directly replaced by the new data. This approach does not keep track of historical changes and only reflects the most recent values. It is a simple and efficient way to update data but lacks the ability to analyze historical trends or track changes over time.

A router transformation in SQL acts like a CASE.. WHEN statement. It allows you to define conditions and corresponding actions to be taken based on those conditions. The router transformation routes data to different output groups based on the specified conditions, similar to how a CASE.. WHEN statement evaluates conditions and executes corresponding statements. Therefore, the correct answer is Router.

The INSTR function in most programming languages is used to find the position of a substring within a string. In this case, the function is searching for the letter 'a' within the string 'Samsung'. Since the letter 'a' appears at the second position in the string, the output of the INSTR function would be 2.

The expression "IN('dog', 'cat', 'dog', 'horse', 0)" checks if the value 0 is present in the given list of values ('dog', 'cat', 'dog', 'horse'). Since 0 is present in the list, the output of the expression is 0.

The correct answer is that :EXT is required when you write an expression that includes a return value from an External Procedure transformation.

A static lookup cache is read-only because it contains fixed values that do not change during runtime. This type of cache is typically used for reference data that remains constant, such as country codes or product categories. The values in a static lookup cache are loaded and stored in memory when the cache is initialized, and they are not modified or updated thereafter. Therefore, any attempt to modify or write to a static lookup cache will result in an error.

The function ADD_TO_MONTH is not a date function. The other options, ROUND, TO_DATE, and TRUNC, are all date functions commonly used in programming languages to manipulate and format dates. However, ADD_TO_MONTH does not exist as a built-in date function and is therefore not a valid option.

Event-Wait is the task that waits for a user-defined or predefined event to occur. Once the event occurs, the Integration Service completes the rest of the workflow. This task is used to synchronize the workflow with external events or conditions. It allows the workflow to pause until the specified event is raised, and then continues the execution.

The default source option for update strategy is "Date Driven". This means that the update strategy will determine whether a record should be updated or inserted based on the date information in the source data. If the date in the source data is more recent than the date in the target system, the record will be updated. If the date in the source data is older or equal to the date in the target system, the record will be inserted.

If the second date is earlier than the first date when comparing using the date_compare function, the function will return the value 1.

A mapplet is a set of transformations that can be reused in multiple mappings. It allows us to create a group of transformations and save them as a single object, which can be easily added to different mappings. This helps in reducing redundancy and improving efficiency in the ETL (Extract, Transform, Load) process.

Type2 SCD method tracks historical data by creating multiple records. In this method, when a change occurs in a dimension attribute, a new record is created with the updated attribute values, while the existing record is marked as inactive or expired. This allows for the preservation of historical data and enables analysis of changes over time. Unlike type1 SCD method, which overwrites the existing record with the updated attribute values, type2 method maintains a history of changes by creating new records.

The functions ROUND, TO_DATE, and TRUNC are all date functions commonly used in SQL. However, ADD_TO_MONTH is not a valid date function. There is no built-in function in SQL called ADD_TO_MONTH.

The comparison operators are used to compare two values and determine their relationship. The "==" operator is the equality operator, which checks if two values are equal. It is not a comparison operator because it does not compare the values in terms of greater than, less than, or any other relationship. Instead, it simply checks for equality.

Yes, the sorter transformation can be passive. The sorter transformation in Informatica is used to sort data based on specified sort keys. It can be active or passive depending on the requirement. In passive mode, the sorter transformation does not change the number of rows or the row values. It only reorders the data based on the sort keys. This means that it does not require any additional resources or processing power. Therefore, the statement "Yes" is correct in stating that the sorter transformation can be passive.

The DATE_COMPARE function is used to compare two dates and it returns an integer value. This means that when using this function, it will compare the two dates and provide a result in the form of an integer, indicating the relationship between the two dates (e.g., whether one is greater than, equal to, or less than the other). The function does not compare strings or numeric values, and it does not return a date or a string value.

A detail outer join keeps all rows of data from the detail source and the matching rows from the master source. This means that even if there are no matches in the master source, the rows from the detail source will still be included in the result.

Sql is the only transformation that works on relational sources. SQL (Structured Query Language) is a programming language designed for managing data held in relational database management systems (RDBMS). It allows users to query, manipulate, and manage relational databases effectively. The other options, lookup, union, and joiner, are generic transformations that can work with various types of data sources, not just relational sources.

A repository domain consists of a single global repository and any number of local repositories. This means that there is only one global repository in the domain, which stores the main version of the code, and there can be multiple local repositories that are synchronized with the global repository. This allows for collaboration and version control within a team or organization.

The load types in Informatica session are Bulk and Normal. The Bulk load type is used for loading large amounts of data quickly, while the Normal load type is used for loading data in a regular manner. Both load types are commonly used in Informatica sessions depending on the specific requirements of the data loading process.

TO_MONTH is not a conversion function because it is not a standard function used to convert data types. The other options, TO_DECIMAL, TO_NUMBER, TO_INTEGER, and TO_DATE, are commonly used conversion functions in various programming languages and databases.

The correct format of the ADD_TO_DATE function is ADD_TO_DATE( ORDER_DATE, 'MM', 1 ). This format follows the syntax of the function, where the first parameter is the date to which we want to add, the second parameter is the interval we want to add (in this case, 'MM' represents months), and the third parameter is the number of intervals to add (in this case, 1 represents adding 1 month to the ORDER_DATE).

The "if" statement can test multiple conditions. It allows for the execution of a block of code if a certain condition is true. It can also be followed by an "else if" statement to test additional conditions, or an "else" statement to provide a default action if none of the conditions are met. Therefore, the "if" statement is the correct answer for this question.

The IIF function is used to evaluate a condition and return different values based on the result. In this case, the condition is whether the average salary is greater than 20000. If it is true, the function will return 1, otherwise it will return 0. Since the IIF function can be used in any transformation, including aggregator transformations, the statement can be set in an aggregator transformation.

The REPLACECHR function is used to replace characters in a string with other characters. In this case, the function is replacing the characters '[' and ']' with NULL (empty space) in the string 'Informatica[Scenarios]'. So, the output will be 'InformaticaScenarios', which is the original string without the square brackets.

The REPLACECHR function replaces a specified character or substring within a string with another character or substring. In this case, the function is replacing the first occurrence of "RAR" with "RM" in the string. Therefore, the return value of the expression will be "RAM".

The LPAD function is used to left pad a string with a specific character or characters. In this case, the string "Informatica" is being left padded with the characters "*..*". The resulting output will be "*..*.Informatica" because the string "Informatica" is inserted after the left padding characters.

The word "KILLED" is not a reserved word in Informatica. Reserved words are predefined keywords in a programming language that have special meanings and cannot be used as identifiers or variable names. In this case, "NOTSTARTED", "STARTED", "STOPPED", and "SUCCEEDED" are all reserved words in Informatica, but "KILLED" is not.

The Load Manager creates log files.

The correct answer is "Update each row flagged for update if it exists in the target table." This means that only the rows that are flagged for update and already exist in the target table will be updated. Rows that are new or do not exist in the target table will not be updated.

If the group by column is not used in the Aggregator, the output will be the only last row. This means that the Aggregator will consider all the rows in the input, but it will only produce the result based on the values of the last row. The previous rows will not be taken into account. Therefore, the output will only contain the data from the last row of the input.

The transformation language provides two comment specifiers: "//" and "--". These can be used to insert comments in expressions.

In case of less amount of data and the need to recover the session, the normal load type should be used. This load type strikes a balance between verbosity and efficiency, making it suitable for smaller data sets. Verbose load type may provide excessive details, while bulk load type is typically used for larger data sets. Therefore, normal load type is the appropriate choice in this scenario.

Yes, we can use the mapping parameter or variable created in one mapping into other reusable transformations. This allows us to share and reuse the same parameter or variable across multiple mappings, improving efficiency and consistency in data transformations.

Filter transformation acts as a 'where' condition in data integration tools, allowing only the rows that meet the specified condition to pass through. It can be used to filter out unwanted data based on a single condition. However, it is not capable of passing multiple conditions simultaneously. Therefore, the statement "Can't passes multiple conditions" is correct about filter transformation.

A code page contains encoding, not decoding, to specify characters in a set of one or more languages. Encoding is the process of converting characters into a specific representation, such as numeric values or binary codes, while decoding is the process of converting these representations back into characters. Therefore, the given answer correctly states that decoding is not a function of a code page.

Hybrid SCD stands for Hybrid Slowly Changing Dimension. It is a combination of Type 1 and Type 2 Slowly Changing Dimensions. Type 1 SCD overwrites the existing data with the new data, while Type 2 SCD keeps track of historical changes by creating new records. Therefore, a hybrid SCD combines the features of both types, allowing for both updates and historical tracking in the same dimension table.

The built-in constants in programming languages are predefined values that cannot be changed during the execution of a program. In this question, the options "Null", "True", "false" are all examples of built-in constants as they represent special values like null, true, and false respectively. The option "ltrim" is not a built-in constant, but rather a function or method used for trimming whitespace characters from the left side of a string. Therefore, "ltrim" is the correct answer as it does not fit the definition of a built-in constant.

The types of groups in Router transformation are user defined group and default group. User defined group allows the user to define custom groups based on specific criteria or conditions. Default group is a group that includes all the rows that do not meet any of the user defined group criteria.

DTS (Data Transformation Services) is not a reporting tool. It is a data integration tool used for extracting, transforming, and loading data between different systems. Analysis Services, Essbase, and BO (Business Objects) are all reporting tools commonly used for data analysis and reporting purposes.

In a session with the Bulk load type, it is not possible to recover the session or rollback any changes made. This load type is typically used for large amounts of data and is optimized for performance rather than transactional integrity. Therefore, any changes made during a Bulk load cannot be undone or recovered.

The default informatica server cache for look-up is the static cache. Static cache stores the entire lookup table in the memory before the session begins and remains unchanged throughout the session. It provides faster data access as it eliminates the need to fetch data from the database repeatedly. Static cache is suitable when the lookup table is small and does not change frequently.

The dimension that is a collection of random transactional codes, flags, and/or text attributes is the "junk" dimension. This dimension is used to store miscellaneous or unrelated attributes that do not fit into any other dimension. It helps in reducing the complexity of the main dimensions by separating out unrelated attributes into a separate dimension.

The correct answer is "Delete Lock" because a delete lock is not a type of lock on repository objects. Execute lock, fetch lock, save lock, and read lock are all common types of locks used to control access and modifications to repository objects. However, a delete lock is not typically used as a separate type of lock, as the act of deleting an object usually involves other types of locks or permissions. Therefore, "Delete Lock" is the correct answer as it does not belong to the category of locks on repository objects.

To generate a single look-up by using multiple tables, one can write a SQL override. This involves overriding the default SQL query generated by the lookup transformation and writing a custom SQL query that joins multiple tables to fetch the desired data. This allows for more flexibility and control in retrieving data from multiple tables in a single look-up operation.

The correct answer is -1 because the date_compare function returns -1 when the first date is earlier than the second date.

The LPAD function is used to pad a string with a specified character or characters on the left side. In this case, the function is applied to the number 190 with a desired output length of 5 and the character '0' as the padding character. The function will add four '0' characters to the left side of the number, resulting in the output "00190".

The statement is correct because in a Union transformation, two tables can be joined even if they do not have common ports. The Union transformation combines the rows from both tables and outputs a single result set. This is useful when you want to merge data from different sources or tables into a single output.

The LENGTH function is not a data cleansing function. Data cleansing functions are typically used to clean and standardize data, such as removing duplicates, correcting formatting errors, or converting data types. The LENGTH function, on the other hand, is used to determine the length of a string or the number of characters in a text field. While it can be useful for data analysis or validation purposes, it does not directly clean or transform data.

The correct answer is that CHR returns the ASCII character corresponding to the numeric value. This means that when given a numeric value, the CHR function will return the corresponding ASCII character. For example, if the numeric value is 65, the CHR function will return the character 'A', as 65 is the ASCII value for 'A'.

The answer is "No" because a sequence generator can only generate numeric values in a sequence. It cannot generate alpha-numeric values, which include both letters and numbers.

The cache that allows you to share lookup cache among multiple transactions is the "Shared" cache. This type of cache can be accessed by multiple transactions simultaneously, allowing them to share the cached data and improve performance by avoiding redundant lookups. This is particularly useful in scenarios where multiple transactions need to access the same data frequently, as it eliminates the need for each transaction to perform its own lookup.

The INSTR function in Informatica is used to find the position of a substring within a string. In this case, the substring "a" is being searched within the string "informatica". The function is being called with the starting position as -1, which means it starts searching from the end of the string. The last parameter, 2, specifies that the search should be case-sensitive. Since the substring "a" is found at position 5 in the string "informatica", the output of the function would be 5.

A rapidly changing dimension refers to a dimension in a data warehouse that frequently undergoes updates or changes. This type of dimension is used to track historical changes in data over time. However, all the other options mentioned in the question are valid types of dimensions. A confirmed dimension represents a dimension that has been verified and validated. A junk dimension combines multiple low-cardinality attributes into a single dimension to reduce the number of dimensions in a data model. A degenerated dimension is a dimension that is derived from a fact table and does not have its own separate dimension table.

The logical OR operator (||) returns the first truthy value it encounters. In this case, 'alpha' is a truthy value, so it is returned as the result.

A "Simple Pass Through" wizard is used to load a static fact or dimension table by inserting all rows. This means that the wizard simply passes the data from the source to the target without any transformation or filtering. It is a straightforward method of loading data where all rows are inserted as they are into the target table.

The default join of the Source Qualifier is an Inner-equi join. This means that only the matching rows from both tables are included in the result set. Non-matching rows are excluded.

The given answer "MM" is not a date format string because it represents the month in two digits format. Date format strings are used to specify the format in which dates are displayed or interpreted. "SS" and "SSSS" represent the seconds, "MM" represents the month, "MON" and "MONTH" represent the month name, "MI" represents the minutes, and "HH", "HH12", and "HH24" represent the hour in different formats.

Look up is a term used to describe the process of retrieving data from a table or database based on a specific search criteria. While the act of performing calculations may not be the primary purpose of a lookup, it is possible to perform calculations using the retrieved data. This can be done by using formulas or functions in spreadsheet software or by writing code in programming languages to manipulate the data obtained from the lookup. Therefore, it is possible to perform calculations in a lookup.

Tracing level refers to the level of detail or verbosity in the information stored in a log file. When the tracing level is set to store data in a log file, it means that detailed information about the execution of a program or system is being recorded in a log file. This can include information such as debug messages, error messages, and other relevant data that can be used for troubleshooting and analysis purposes. Storing data in a log file allows developers and administrators to review and analyze the log file later to understand the behavior of the system and identify any issues or errors that occurred during its execution.

The ROUND() function is used to round a number to a specified number of decimal places. In this case, the number 10567.90 is being rounded to the nearest hundredth place (-2 decimal places). Since the digit in the hundredth place is 5, which is greater than or equal to 5, the number is rounded up. Therefore, the output of this statement is 10500.

The INSTR function in SQL is used to find the starting position of a substring within a string. In this case, the function is searching for the substring 'a' within the string 'Vivek'. Since there is no occurrence of 'a' in 'Vivek', the function will return 0 as the output.

ERP (Enterprise Resource Planning) is not a target option for file on the servers. ERP is a software system used by organizations to manage and integrate various aspects of their business, such as finance, human resources, and supply chain. It is not specifically designed for file storage or transfer like the other options mentioned (FTP, Loader, MQ). ERP systems are typically used for data management and processing within an organization, rather than for file-related operations.

The effective time range is not a method used to recognize newly added rows in Type2 mapping. Version number, effective date range, and flag value are commonly used to identify and track changes in the data. The effective time range refers to the period during which a particular row is considered valid or active in the database. It is not directly related to recognizing newly added rows.

Data marts are designed to cater to the specific needs of a single subject area within an organization. They are smaller and more focused than data warehouses, allowing for easier and quicker access to relevant data for decision-making purposes. Unlike data warehouses, data marts are not optimized for INSERT and UPDATE operations, as their main purpose is to provide a consolidated view of data related to a particular subject area. Therefore, the correct answer is that data marts are generally designed for a single subject area.

The types of batches are concurrent and sequential. Concurrent batches refer to multiple tasks or processes that can be executed simultaneously, allowing for parallel processing and increased efficiency. Sequential batches, on the other hand, involve executing tasks or processes one after another, following a specific order or sequence.

A sequence generator is not an active transformation because it does not change or modify the data in any way. Instead, it generates a sequential number for each row of data. Active transformations, on the other hand, perform operations that alter the data, such as filtering, aggregating, or joining. Normalizer, SQL, and stored procedure are all examples of active transformations as they manipulate the data in some way.

If you want to insert new rows into cache and the target, you should use the Dynamic cache. Dynamic cache allows for the addition of new rows into the cache and the target, providing flexibility and adaptability to the changing data. Static cache, on the other hand, does not allow for the insertion of new rows, as it is designed to store a fixed set of data. Persistent cache is used to store data permanently, while Re-Cache is not a recognized term or option in this context.

Sorted input option can be used for incremental aggregation. This option allows the input data to be sorted based on the aggregation key before performing the aggregation process. This helps in optimizing the aggregation process as it reduces the amount of data shuffling and improves the performance. By using the sorted input option, the incremental aggregation can be efficiently performed on the sorted data, resulting in faster and more efficient processing.

In a joiner transformation, the settings that need to be configured are the master and detail source, the condition of the join, and the type of join. The master and detail source specify the tables or sources that are being joined together. The condition of the join determines how the records from the master and detail sources are matched. The type of join specifies whether it is an inner join, outer join, or full outer join. These settings are crucial in determining how the join operation is performed and what results are obtained.

During a session running, various files are generated to track the progress and identify any errors or issues. The session log keeps a record of the session's activities and can be used for debugging purposes. The workflow log records the details of the workflow execution. The error log captures any errors encountered during the session. The bad files store data that fails to meet certain criteria. However, cache files are not created during session running. They are used to store temporary data for faster access and are typically created during the workflow design process.

Joiner will not match a null value. When joining tables, a null value in one table will not match with any value in the other table, including another null value. Therefore, in this scenario, the joiner will not match the null value in EMP_ID1 with the null value in EMP_ID2.

In a software development environment, a repository manager is responsible for managing the storage and retrieval of code and other digital assets. One of the tasks of a repository manager is to handle locks on objects, ensuring that only one user can make changes to an object at a time. Therefore, if one object is locked, the repository manager is the appropriate place to release the lock. The workflow manager and designer may not have the necessary functionality to release locks, and the "None of these" option is incorrect as the repository manager is the correct choice.

The given answer is correct because in boolean logic, when one of the operands is NULL, the result is always NULL. Therefore, NULL AND TRUE will result in NULL, and NULL AND FALSE will result in FALSE.

The value returned by the NewLookupRow port as 0 indicates that the Integration Service will not update or insert the row in the cache.

The wizard that loads a slowly growing fact or dimension table by inserting new rows is the "Slowly Growing Target" wizard. This wizard is designed specifically for tables that experience a gradual increase in data over time. It allows for efficient and optimized insertion of new rows into the table, ensuring that the loading process does not impact the overall performance of the database.

The option "Update as Delete" is not an option in the update-strategy. Update strategies typically involve updating or inserting data, but not deleting data. Therefore, "Update as Delete" is not a valid option in the update-strategy.

The value returned by the NewLookupRow port that says the Integration Service inserts the row into the cache is 1.

In Workflow Manager, the repository objects that are created include database connections, worklets, and sessions. However, maplets are not created in Workflow Manager. Maplets are reusable objects that are created in the Mapping Designer and can be used in multiple mappings.

The options given are different types of target types on the server. File, Relational, and ERP are all valid target types on the server. However, VSAM is not a valid target type on the server.

The INSTR function is used to find the position of a substring within a larger string. In this case, the function is searching for the second occurrence of the letter 'a' in the string "I am a informatica Developer". Since the second occurrence of 'a' is at position 6, the output of the function is 6.

A transformation is a repository object that generates, modifies, or passes data. It is used to manipulate data as it flows from source to target in an ETL (Extract, Transform, Load) process. Transformations can perform various operations such as filtering, aggregating, joining, and sorting data. They are essential for data integration and data transformation tasks in data warehousing and business intelligence systems.

Informatica Repository Manager does not have a specific repository type called "User Defined". This means that there is no option to create a custom or user-defined repository in Informatica Repository Manager.

The function CELI rounds a number up to the nearest integer. Therefore, CELI(12.39) would round up to 13, as it is closer to 13 than to 12. CELI(-12.39) would round down to -12, as it is closer to -12 than to -13. Similarly, CELI(12.56) would also round up to 13.

The use of target loader is to determine the order in which data is loaded into the dimension and fact tables. In this case, the correct answer states that the data is first loaded into the dimension table and then into the fact table. This order is important because the dimension table contains the reference data that is needed for the fact table, which contains the actual data. By loading the dimension table first, the necessary reference data is available when loading the fact table.

The Integration Service suspends the workflow if any of the tasks mentioned (Session, Command, Worklet, Email) fail. This means that if any one of these tasks encounters an error or does not complete successfully, the Integration Service will pause the workflow to prevent further execution until the issue is resolved.

The statement "multiple level of extraction of data" is not true of a Cube. A Cube is a multidimensional representation of data that is used for analysis purposes and provides multiple views of the data. However, it does not involve multiple levels of extraction of data.

The FLOOR function rounds a number down to the nearest integer. FLOOR(39.9) would be 39 because it is rounding down to the nearest whole number. Similarly, FLOOR(-39.9) would be -40 because it is rounding down to the nearest whole number in the negative direction. FLOOR(39.2) would also be 39 because it is rounding down to the nearest whole number.

The functions TRUNC, LN, and ROUND are all numeric functions because they perform calculations or manipulations on numbers. However, AVG is not a numeric function, but rather a statistical function used to calculate the average of a set of numbers.

The meaning of "Update as update else Insert" in the update-strategy is that it will first try to update the row if it exists in the target table. If the row does exist, it will be updated. However, if the row does not exist, it will be inserted as a new row. This update strategy ensures that the row is either updated or inserted, depending on its existence in the target table.

The function that causes the Integration Service to skip a record and issue the specified error message is "ERROR". When this function is used, the Integration Service will encounter an error in processing a record and instead of aborting the entire process, it will skip that particular record and continue with the rest of the data. This allows the integration process to continue running without interruption, while still providing information about the error that occurred.

A nested aggregate function is a function that takes multiple input rows and returns only one output row. This means that the function performs calculations or operations on a group of rows and produces a single result for that group. This is commonly used in SQL queries when performing calculations on grouped data, such as calculating the average or sum of a column for each group. By using a nested aggregate function, the result is condensed into a single row, making it easier to interpret and analyze the data.

A mapplet in Informatica is a reusable object that contains a set of transformations. It can be used in multiple mappings to perform input and output transformations on data. This means that a mapplet contains both input and output transformations, making it the correct answer to the question. Reusable transformations and reusable mappings may contain transformations, but they do not specifically mention input and output transformations, so they are not the correct answer.

The given options are all related to versions of objects in a repository. However, updating a version is not a valid action in this context. Versions are typically updated by creating a new version, rather than directly updating an existing one. Therefore, "Update a version" is not a valid option for versions of objects in the repository.

The types of methods to load a dimensional table are conventional and direct. Conventional loading involves loading data from a staging area into the dimensional table using SQL queries or ETL (Extract, Transform, Load) processes. Direct loading, on the other hand, involves directly inserting data into the dimensional table without the need for a staging area.

Type 3 SCD (Slowly Changing Dimension) stores one-time historical data with current data. In this type, a new row is created for each change in the dimension attribute, allowing the storage of historical data. The old attribute value is updated in the existing row, while the new attribute value is added to a new row. This way, the current data is always available, along with limited historical data.

The correct answer is Event-Raise because it represents the action of raising or triggering a user-defined event. This task is typically used to notify the system or other components about a specific event occurring in the workflow. It allows the user to define custom events and specify the conditions under which they should be raised.

The function "trunc" is used to convert dates to a specific year, month, day, hour, or minute. It allows the user to truncate the date and time portion of a given date, keeping only the desired part.
