To determine what a relational database consists of, we need to understand the primary components that make up this type of database system.

1. Records: These are individual entries that contain data within a table, often corresponding to a single data item in a relational database. Each record represents a row in the table.

2. Tables: These are the main structure of a relational database. A table is organized into rows and columns and is used to store related data. Each table can be thought of as a different entity.

3. Fields: These are the individual columns in a table, representing a single attribute of the data being stored (for example, a name or an age).

4. Keys: These are attributes that help uniquely identify records in a table, such as primary keys or foreign keys.
