Efdb is the structure of SQL, everyone is type (class), but sometimes there is a lot of repetition, so there will be inheritance (abstract)

Primitive types are string, int, datetime, date

There can be other types in the type, if the type is complex is a collection (specification), list (which is a many-to-many or one-to-many relationship), enum
