What system applications modifies data the instance it receives it?

OLAP
OLTP
HDFS
RDBMS

Correct Answer

A. OLTP

Explanation

OLTP (Online Transaction Processing) is the system application that modifies data the instance it receives it. OLTP systems are designed to handle real-time transactional processing, where data is constantly being updated and modified. These systems are commonly used in industries such as banking, e-commerce, and customer relationship management (CRM), where immediate data modification is crucial for accurate and up-to-date information. Unlike OLAP (Online Analytical Processing) systems that focus on complex data analysis and reporting, OLTP systems prioritize quick and efficient data modification for transactional purposes. Therefore, OLTP is the correct answer to the given question.

Which of these is the fastest method of loading Dimensional tables?

Conventional
Direct
Top
Fast

Correct Answer

A. Direct

Explanation

The correct answer is "Direct." Direct loading is the fastest method of loading Dimensional tables because it bypasses the staging area and loads data directly into the target table. This eliminates the need for additional processing and transformations, resulting in faster loading times.

Which of these objects can be used in a mapplet?

Joiner transformation
Target definition
Procedures
Reusable sequence transformation

Correct Answer

A. Reusable sequence transformation

Explanation

A mapplet is a reusable object in Informatica PowerCenter that contains a set of transformations. It can be used in a mapping to perform a specific task. The Joiner transformation is used to join two sources based on a common key and is typically used in a mapping, not a mapplet. The Target definition represents the target table structure and is also not used directly in a mapplet. Procedures are not used in mapplets either. On the other hand, a Reusable sequence transformation is a transformation that can be used in a mapplet. It allows you to define a sequence of transformations that can be reused across multiple mappings.

What is the difference between mapping parameter and mapping variable?

Mapping parameter does not have a value while mapping variable has a value
Mapping parameter has a value while mapping variable does not have a value
Mapping parameter is dynamic while mapping variable is static
Mapping parameter is static while mapping variable is dynamic

Correct Answer

A. Mapping parameter is static while mapping variable is dynamic

Explanation

Mapping parameter is a static object in a data mapping process, meaning it does not change its value during the execution of the mapping. On the other hand, a mapping variable is dynamic and can be assigned a value based on certain conditions or calculations during the mapping process. Therefore, the correct answer is that mapping parameter is static while mapping variable is dynamic.

What are the two types of data movement modes in Informatica?

Unicode and multi-code
ASCII and multi-code
ASCII and unicode
ASCII and binary

Correct Answer

A. ASCII and unicode

Explanation

The correct answer is ASCII and unicode. ASCII is a character encoding standard that represents text in computers, telecommunications equipment, and other devices. It uses a 7-bit encoding scheme and includes characters such as letters, numbers, and symbols commonly used in the English language. Unicode, on the other hand, is a universal character encoding standard that can represent characters from all major scripts and languages. It uses a variable-length encoding scheme and includes a much larger range of characters compared to ASCII. In Informatica, these two data movement modes are used to handle different types of data and ensure compatibility between systems.

What is MDM?

Machine Data Management
Master Database Management
Machine Database Management
Master Database Management

Correct Answer

A. Master Database Management

Explanation

MDM stands for Master Database Management. This refers to the practice of managing and controlling a master database, which is a centralized repository that stores and organizes important data for an organization. Master databases are typically used to store critical information such as customer data, product data, and employee data. By effectively managing the master database, organizations can ensure data accuracy, consistency, and integrity across different systems and applications. This helps in improving data quality, facilitating data integration, and supporting various business operations and decision-making processes.

Which of these repositories is within a domain?

Global repository
Standalone repository
Local repository
Domain repository

Correct Answer

A. Local repository

Explanation

A local repository is within a specific domain, meaning it is located within a particular network or organization. It is used to store and manage code or files that are specific to that domain, allowing for easier collaboration and version control among team members. Unlike a global repository, which is accessible from anywhere, a local repository is limited to a specific domain or network.

Which of these determines how PowerCenter handles character data?

Character mode
Data movement mode
Data mode
ASCII mode

Correct Answer

A. Data movement mode

Explanation

The data movement mode determines how PowerCenter handles character data. This mode determines whether the data is treated as ASCII or Unicode, and whether it should be converted or not during data movement. It affects how the data is read from source systems and how it is written to target systems.
