In a database, what is the largest unit?

• A. File
• B. Record
• C. Table
• D. Field

Answer: (A)

Data is organized in layers: a field is a single data value, a record is a row of fields, and a table is a collection of records. A file acts as the storage container that can hold one or more tables and their data. Because a file can contain multiple tables and all their records, it is the largest unit among the options. The other elements are contained within a file: a table holds many records; each record holds several fields; a field is the smallest data unit.
