Database Concepts Exam Quiz: Trivia!

A primary key is used to uniquely identify each record in a table. It is a field or a combination of fields that uniquely identifies a record in a database table. The primary key ensures that each record in the table is uniquely identifiable and helps in maintaining data integrity and consistency. It is used for referencing and linking records between different tables in a relational database system.

Design View is the correct answer because it allows users to modify the design of a table. In Design View, users can make changes to the table structure, such as renaming fields or changing the data type of a field. This view provides a more detailed and customizable interface for designing and modifying tables compared to other views like Datasheet View, Table View, or Wizard View.

The correct answer is Date/Time. This data type is used to store both date and time values. It can store values between the years 100 through 9999, allowing for a wide range of dates and times to be stored and manipulated in a database or program.

Forms are used to provide a user-friendly interface for entering data into tables. They allow users to input data in a structured manner, making it easier to store and organize information. Forms typically include fields and controls that guide users in entering the required data, ensuring accuracy and consistency. By providing a user-friendly interface, forms enhance the user experience and facilitate efficient data entry into tables.

The correct answer is "Row Selector". In the figure, x represents the element or component that is used to select a particular row in a table or dataset. It allows the user to choose a specific row for further actions or operations. The term "Row Selector" accurately describes the function and purpose of this element in the given figure.

In the design view of a table, you can select multiple fields by using the Ctrl key. This key allows you to select multiple fields at once, which can be useful for making changes or applying formatting to multiple fields simultaneously. By holding down the Ctrl key and clicking on each field, you can quickly select multiple fields without having to individually select each one. This can save time and make it easier to work with tables in the design view.

A single set of related data values is referred to as a record. In a database, a record represents a complete set of information about a specific entity or item. It is composed of multiple fields, each containing a specific data value that provides details about the entity. For example, in a customer database, a record may include fields such as name, address, phone number, and email. By organizing data into records, it becomes easier to retrieve and manage information efficiently.

False. A table can have multiple primary keys, known as composite keys, which are made up of two or more columns. Composite keys are useful when a single column cannot uniquely identify a row in a table.

The correct answer is "Like 'S*'". This validation rule will ensure that the StudentID starts with the letter "S" and can be followed by any combination of characters. The use of the wildcard "*" allows for any number of characters to come after the letter "S".

The Caption field property can be used to achieve displaying the StudentAddress field as Address in the datasheet view of the Student table. This property allows for the customization of the field label or name that is displayed in the datasheet view, providing a more user-friendly and descriptive label for the field.
