    • One-to-one

    • Many-to-one

    • One-to-many

    • Many-to-many

    Correct Answer
    A. Many-to-many
    Explanation
    A many-to-many relationship in an entity-relationship (E-R) model allows for one entity occurrence of the first type to be related to zero, one, or multiple occurrences of the second type, and vice versa. This means that multiple entities of the first type can be associated with multiple entities of the second type, creating a many-to-many relationship between them.

    A decision tree is characterized by 

    • Displaying a large set of iterative primitives

    • Portraying structured text, program definition, or program design language

    • Displaying one or more sets of actions that are executed based on the state of conditions (true or false)

    • Portraying a hierarchy of independent conditions and the activities resulting from each valid combination of conditions

    Correct Answer
    A. Portraying a hierarchy of independent conditions and the activities resulting from each valid combination of conditions
    Explanation
    A decision tree is a graphical representation that portrays a hierarchy of independent conditions and the activities resulting from each valid combination of conditions. It helps in decision-making by providing a clear and structured visualization of different possible outcomes based on different conditions. By following the branches of the tree, one can determine the appropriate actions to be taken based on the current state of conditions (true or false). This hierarchical structure allows for easy understanding and evaluation of different scenarios, making decision trees a popular tool in various fields such as data analysis, machine learning, and problem-solving.

    What is an algorithm used for?

    • Governing the transformation of input data flows into output data flows

    • Displaying one or more sets of actions that are executed based on the state of conditions (true or false)

    • Outlining the final solution that you must translate into a specific programming language with syntactical structures

    • Portraying a hierarchy of independent conditions and the activities resulting from a valid combination of conditions

    Correct Answer
    A. Outlining the final solution that you must translate into a specific programming language with syntactical structures
    Explanation
    An algorithm is used to outline the final solution that needs to be translated into a specific programming language with syntactical structures. It provides a step-by-step procedure or set of instructions to solve a problem or perform a task. The algorithm serves as a blueprint or plan for implementing the solution in a programming language, ensuring that the code follows the correct syntax and structure.

    What are reserved words?

    • Algorithms written in structured english

    • Words you can express using specific parameters

    • Algorithms and syntax used in a particular programming language

    • Words having special meaning to a particular programming language

    Correct Answer
    A. Words having special meaning to a particular programming language
    Explanation
    Reserved words are words that have a special meaning in a particular programming language. These words are predefined and cannot be used as identifiers or variable names in the code. They are reserved for specific purposes, such as defining control structures, data types, or keywords in the language syntax. Using reserved words inappropriately can lead to syntax errors and confusion in the code. Therefore, it is important for programmers to be aware of and avoid using reserved words in their code.

    What is an iterative primitive solution?

    • Step-by-step processing

    • A hierarchy of independent conditions

    • Code structured for repetitive execution

    • Alternative steps that may or may not be executed

    Correct Answer
    A. Code structured for repetitive execution
    Explanation
    An iterative primitive solution refers to code that is structured in a way that allows for repetitive execution. This means that the code is designed to be executed in a loop or iteration, where a certain block of code is repeated multiple times until a specific condition is met. This approach is commonly used in programming to perform repetitive tasks efficiently and reduce code duplication. It allows for step-by-step processing and ensures that the same set of instructions is executed repeatedly until the desired outcome is achieved.

    Data items arranged in the order in which they are stored and the same manner that they will be addressed describes the use of a/an

    • Linked list

    • Ordered list

    • Network list

    • Hierarchical list

    Correct Answer
    A. Ordered list
    Explanation
    An ordered list is a data structure where the data items are arranged in a specific order, usually based on their values or keys. The order of the items in the list corresponds to the order in which they are stored in memory and the order in which they will be accessed. This allows for efficient searching and retrieval of items based on their position in the list. In contrast, a linked list does not necessarily have a specific order, a network list refers to a different type of data structure, and a hierarchical list organizes items in a hierarchical structure rather than a linear order.

    A tree structure is best used to display database records that have what type of fields?

    • Repetetive

    • Duplicate

    • Indexed

    • Pointer

    Correct Answer
    A. Repetetive
    Explanation
    A tree structure is best used to display database records that have repetitive fields. This is because a tree structure allows for efficient organization and retrieval of data that has repeating or hierarchical patterns. Each node in the tree represents a record, and the branches represent the relationships between the records. This structure is particularly useful when dealing with data that has a parent-child relationship or when there are multiple instances of the same type of data.
