A Review of Database Schemas
نویسنده
چکیده
The purpose of this note is to review the traditional set of schemas used in databases, particularly as regards how the conceptual schemas affect the design of the storage of relations. It is sometimes considered that each base relation must be stored ‘as is’, i.e. each logical tuple must be mapped directly to a corresponding physical record. This is not so, and some relational DBMS products already provide some facilities to improve on this. The results of the review lead to a rationalisation of the database schema architecture.
