    ____________ Means duplication of data.

    Explanation
    Redundancy refers to the duplication of data. When data is repeated or duplicated in a system, it is considered redundant. This can occur in databases, computer systems, or any other form of data storage. Redundancy can be intentional, such as when data is intentionally copied for backup purposes, or it can be unintentional, resulting from errors or inefficiencies in data management. Regardless of the cause, redundancy can lead to increased storage requirements, slower system performance, and potential inconsistencies or conflicts in the data.

    A field name can have a full stop.

    • False

    • True

    Correct Answer
    A. False
    Explanation
    A field name cannot have a full stop because a full stop is a reserved character in programming languages and is used for various purposes such as indicating object properties or calling methods. Using a full stop in a field name would cause confusion and errors in the code. Therefore, the statement is false.

    Field names can start with a blank space?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Field names cannot start with a blank space. In programming and database systems, field names are identifiers that are used to name and reference specific columns or attributes in a table or data structure. In most programming languages and databases, identifiers cannot begin with a blank space. They typically need to start with a letter or an underscore, followed by a combination of letters, numbers, and underscores. Starting a field name with a blank space would result in a syntax error.

    Explanation
    The relational database model is the most popular one among all. This is because it allows for the organization and storage of data in a structured manner using tables, rows, and columns. It offers flexibility, scalability, and ease of use, making it widely adopted in various industries. It also supports complex queries and provides a standardized way to access and manipulate data. Relational databases have been around for several decades and have proven to be reliable and efficient for managing large amounts of data.

    • Query

    • Table

    • Report

    • Forms

    Correct Answer
    A. Report
    Explanation
    A report is an object that retrieves data from a database and presents it in a well-organized and easy-to-read format. It allows users to summarize and analyze data, as well as present it in a visually appealing manner. Reports often include tables, charts, and graphs to help users understand the data more effectively. Unlike queries, which retrieve raw data, reports provide a formatted and structured view of the data, making it convenient for users to interpret and make informed decisions based on the information presented.

    Correct Answer
    A. All of them
    Explanation
    In datasheet view, there are multiple ways to move from one column to another. One way is by using the Tab key on the keyboard, which allows you to move to the next column in a sequential order. Another way is by using the right arrow key, which also helps in navigating to the next column. Additionally, you can also use the mouse to click on a specific column to move to it. Therefore, all of these options can be used to move from one column to another in datasheet view.
