    Which of the following data relationships cannot be represented in a relational database?

    • One-to-one

    • Three-to-one

    • One-to-many

    • Many-to-many

    Correct Answer
    A. Many-to-many
    Explanation
    A many-to-many data relationship cannot be represented in a relational database because it violates the rules of normalization. In a many-to-many relationship, multiple records from one table are associated with multiple records from another table. In a relational database, this would require creating a separate table to represent the relationship, known as a junction or join table. This table would contain foreign keys from both tables involved in the relationship. Without this additional table, it would not be possible to accurately represent and maintain the many-to-many relationship in a relational database.

    In a relational table, data in may change frequently within a

    • Key field

    • Non-key field

    • Data entry field

    • Table identification field

    Correct Answer
    A. Non-key field
    Explanation
    In a relational table, a key field is a unique identifier for each record and is used to establish relationships between tables. The data in a key field is typically stable and does not change frequently. On the other hand, a non-key field is any other field in the table that is not used as a unique identifier. The data in a non-key field may change frequently as it represents the actual information being stored in the table. Therefore, the correct answer is non-key field.

    • Chronological

    • Alphabetical

    • Numerical

    • Topical

    Correct Answer
    A. Alphabetical
    Explanation
    The tables within the Relational Database Management System (RDMS) schema are arranged in alphabetical order. This means that the tables are sorted based on their names in ascending order, following the order of the letters in the alphabet. This arrangement makes it easier to locate and access specific tables within the database, as they are organized in a logical and consistent manner.
