POSC Meta Model Specifications Version 2.3 |
Logical Data Model |
This gives the mapping from the logical model to the physical model for entities to tables and rules to column_groups. Attributes to column_groups are handled by att_col_grp_map.
- map_head (M: projection_map(mapping_group))
- The first mapping of the group that this mapping is part of.
- prod_versn (M: prod_versn)
- The projection run that resulted in this mapping.
- ref_proj_meth (M: ref_proj_method(projection_map))
- The projection method used by this mapping. Each projection_map must using projection method one ref_proj_method.
- map_source_s (O: string(19))
- The source of the mapping i.e. the link to the logical model.
- map_target_s (O: string(19))
- The target of the mapping, i.e. the link to the relational side.
- mapping_group (V: SET[0:?] projection_map(map_head))
- The group of projection_maps that this is part of.
