A description of a database design method according to user views is introduced. The database schema is decomposed by applying the operators: horizontal decomposition, vertical decomposition and derived horizontal decomposition. Resulting fragments (= effects of the decomposition) are controlled by a central Data Dictionary, consisting of two subschemata, the Application Subschema and the Data Subschema.
