What are fields in a database?

Fields in a database refer to individual attributes of data. Each field represents a specific piece of information that is stored in a record within a database table. For example, in a table of customer information, fields might include "Customer ID," "Name," "Email," and "Phone Number." Each of these fields holds a particular type of data related to each customer, which is essential for organizing and retrieving information efficiently.

Understanding fields is fundamental for working with databases since they define the structure of the data. They determine what kind of information can be stored and how that information relates to other data within the database. This concept is critical in database management and is widely applicable in various relational database systems.

The other answer options refer to different database concepts. Sets of related records describe tables or entities, methods of data retrieval pertain to querying processes, and types of data validation involve ensuring data accuracy and integrity. While these are important aspects of database management, they do not describe the individual components of the database structure that are known as fields.
