The relational model has three MAJOR aspects:

Structures: Structures are well-defined objects (such as tables, VIEWS, indexes, and so on) that store or access the data of a database. Structures and the data contained WITHIN them can be manipulated by operations.

Operations: Operations are clearly defined actions that allow users to manipulate the data and structures of a database. The operations on a database must adhere to a predefined set of integrity RULES.

integrity rules :Integrity rules are the laws that govern which operations are allowed on the data and structures of a database. Integrity rules protect the data and the structures of a database.
