In a database table, the category of information is called ______a)Tup...
Answer:
The correct answer is C: Record.
A database table is made up of rows and columns, where each row represents a specific record and each column represents a specific attribute or field of that record. The category of information in a database table is referred to as a record. Here is a detailed explanation of the terms used in the question:
- Tuple: A tuple is another term used to describe a row or record in a database table. It represents a single instance of data that is composed of a set of attributes.
- Field: A field is a column or attribute in a database table that holds a specific type of data. It represents a single piece of information within a record.
- Record: A record is a complete set of related information in a database table. It is a collection of fields that represent a specific entity or object.
- All of above: This option is incorrect because it includes all the given terms (Tuple, Field, and Record), which is not accurate. Only the category of information in a database table is referred to as a record.
Therefore, the correct answer is C: Record.

Category of Information in a Database Table
Definition:
- In a database table, the category of information is called a Record.
- A record represents a single instance of data within a table, typically corresponding to a row in the table.
Explanation:
- A Field is a single piece of data within a record, such as a name or a date.
- A Tuple is a row within a table that contains a set of fields representing a single record.
- Therefore, the category of information in a database table is the entire set of data that makes up a single record.
Example:
- In a table of employee information, each record may include fields such as employee ID, name, department, and salary.
- Together, these fields make up the category of information for each employee record in the table.
Conclusion:
- Understanding the concept of records and fields is crucial for organizing and managing data effectively in a database table.
- By properly categorizing information into records, it becomes easier to retrieve, update, and analyze data within the database.
