Users must be able to access the database’s structure (catalog) using the same query language that they use to access the database’s data. The system must support set-at-a-time insert, update, and delete operators. Integrity constraints must be specified separately from application programs and stored in the catalog. It must be possible to change such constraints as and when appropriate without unnecessarily affecting existing applications. Existing applications should continue to operate successfully
