    Rate this question:

  • 3. 

    Data modelling is used for one of these.

    • A.

      Application

    • B.

      Designing

    • C.

      Data requirement analysis

    • D.

      Rewriting

    Correct Answer
    C. Data requirement analysis
    Explanation
    Data modelling is a technique used in the field of data management to analyze and define the data requirements of a system or organization. It involves identifying the entities, attributes, relationships, and constraints within the data and creating a conceptual representation of these elements. This helps in understanding the data needs and designing an efficient and effective database structure. Therefore, data modelling is primarily used for data requirement analysis.

  • 4. 

    The process of creating a data model for an information system is termed?

    • A.

      Programming

    • B.

      Data analysis

    • C.

      Database management

    • D.

      Data modelling

    Correct Answer
    D. Data modelling
    Explanation
    Data modelling is the correct answer because it refers to the process of creating a representation of the data requirements for a specific information system. It involves identifying the entities, attributes, relationships, and constraints of the system and organizing them into a structured format. Data modelling helps in understanding the data flow and structure within the system, which is crucial for designing and developing an efficient and effective information system. Programming, data analysis, and database management are related concepts but not specific to the process of creating a data model.

  • 5. 

    A topic covered in the data modelling test is?

    • A.

      Data system

    • B.

      Data Objects

    • C.

      Analyzing

    • D.

      JavaScript

    Correct Answer
    B. Data Objects
    Explanation
    The topic covered in the data modelling test is data objects. Data objects are entities that represent real-world objects or concepts and are used to store and manipulate data in a database. In data modelling, the focus is on designing the structure and relationships of these data objects to ensure efficient storage and retrieval of information. This involves identifying the attributes and relationships of the objects and creating a logical representation of the data model.

    One of the question types of the data modelling test is the?

    • A.

      App programming

    • B.

      Database

    • C.

      True or False

    • D.

      Media

    Correct Answer
    C. True or False
    Explanation
    The correct answer is "True or False" because the question is asking about the types of questions in the data modelling test, and one of those types is the true or false question.
