DATABASE SCHEMA

摘要

An unlimited number of sets may be persisted and interrelated, while each element of each set has an unlimited collection of properties or attributes, and each element of each set may also have an unlimited collection of transactions which themselves may have an unlimited collection of properties or attributes, by using three types of tables, control data tables, authentication data tables, and data tables, and providing a clear separation between them. Control data tables may define the schema and behavior, authentication data tables may be utilized in access control and security, and data tables may comprise the content of the databases.
