In database terminology, what is a 'record'?

• A. A collection of several database tables
• B. A single entry in a database table, encompassing various attributes
• C. An index of all database entries
• D. A summary of database information

Answer: (B)

A 'record' in database terminology refers to a single entry in a database table that encompasses various attributes. Each record represents a complete set of information for a particular entity, consisting of multiple fields that detail specific attributes related to that entry. For example, in a database table for a library, a record might contain information about one specific book, including its title, author, publication date, and genre. This structure allows for organized data management, where each record can be defined, retrieved, and manipulated as needed.

The other options describe different concepts in database management. While a collection of tables can make up a database, it is more accurate to describe a record as an individual entry. An index refers to a data structure that improves the speed of data retrieval operations on a database table, rather than describing an individual entry itself. Lastly, a summary of database information typically provides an overview rather than a detailed entry, which is what a record is designed to represent.
