In database terminology, the largest unit is a File. Which option best describes a file?

• A. Group of related tables
• B. Single, accessible unit of storage
• C. Entire database
• D. A field within a record

Answer: (B)

Think of a file as the actual storage container on disk that the database uses. It’s the single, accessible unit of storage the DBMS reads from or writes to as a whole. A file can hold many records, and each record consists of fields. This makes it the proper description for a file: it’s the fundamental on-disk storage unit the system manages. A group of related tables is a logical collection, not the storage unit itself. The entire database is a larger construct that may span multiple files. A field is just one piece of data within a single record.
