DBStructDef - Internal structure definition
Inherits:
StructDef
Definitions for data structures are usually read from an ODABA dictionary. However those can be provided and filled directly in main storage. Still in this case the definition should be provided via Dictionary functions to make them available for the ODABA kernel. From an ODABA dictionary structures are provided only, if they are marked as checked and as ready for a non test environment.
