The structure of a database defines how objects are organized in the database. Different data storage structures are used to store objects in databases. For example, the highest-level structure (such as "Catalog" followed by "Schema" and finally by "Table") is not applicable to all database types.

The table below describes the structure of some databases in terms of catalog and schemas:
