POSC Meta Model Specifications Version 2.3 |
Logical Data Model |
This is to cope with EXPRESS enumeration types. We have made an implementation decision to store character strings that are up to 40 characters long.
- parent_type_def (M, K: type_def)
- The name of the enumeration type itself.
- list_member (M, K: string(40))
- The enumerations specified for this type.
- source (M: source)
- The source of this enumeration type.
Local rules:
- Uniqueness Constraint
- parent_type_def, list_member
Entity projects as table ENUM_TYPE.
