Domain type
Keywords: data type
Domain types define the type instances of a property are based on. Domain types can be basic types, but also complex data types or enumerations. The ODMG standard allows locally defined types, which are not yet supported by ODABA, i.e. for defining an ODABA database, embedded definitions for structures (struct_type) or enumerations (enum_type) should not be used.
Definition:
domain_type := simple_type_spec | struct_type | enum_type
