Pronounce
skee-ma, the structure of a
database system, described in a formal language supported by the
database management system (DBMS). In a
relational database, the schema defines the
tables, the
fields in each table, and the relationships between fields and tables.
Schemas are generally stored in a data dictionary. Although a schema is defined in text database language, the term is often used to refer to a graphical depiction of the database structure.
