Data arranged into columns and rows in a database are stored in which structure?

• A. Databases
• B. Tables
• C. Schemas
• D. Records

Answer: (B)

In relational databases, the grid-like arrangement of data with columns representing attributes and rows representing records is stored in a table. A table provides the structure for a set of similar records: each column defines a data type and attribute, while each row holds a complete instance of those attributes. This is why data organized by columns and rows is described as being stored in a table.

It’s useful to keep in mind related terms: a database is the collection of tables (and other objects); a schema defines the structure and relationships of those tables; a record (or row) is a single entry within a table.
