Sinossi

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The schema (pronounced skee-ma) of a database system is its structure described in a formal language supported by the database management system (DBMS). Database schema refers to the organization of data, to create a blueprint, of how a database will be constructed(divided into database tables). The formal definition of database schema is a set of formulas (sentences) that specify integrity constraints imposed on the database. All constraints are expressible in the same language. A database can be seen in terms of logic as a structure in a realization of the database language.
