Structures: Structures are well-defined objects which store the data of a database. Structures and the data contained inside them can be manipulated through operations.
Operations: Operations are clearly described actions which permit users to manipulate the data and structures of a database. The operations on a database must adhere to a pre- described set of integrity rules.
