Data modeling now supports models and subject areas, as well as separate physical modeling. Entity types are automatically transformed as required based on the relationship you draw. Relationships between entities are maintained for whatever diagram they appear on within a model. Data Dictionary of Attributes, Elements, Structures, and Domains Data elements provide the core data dictionary entry. Attributes enable the modeler to enter instance data, such as primary key, foreign key, and nullity information.
Data structures provide the modeler with a way to group data elements.
Data domains may be used optionally to provide data elements with inherited definitions. Grids provide extreme ease of use for modeling attributes of entities. The grid enables you to view the attribute, its data element or structure, and its optional data domain in one pane. You may even optionally expand structures in the grid. Both of these facilities are delivered as part of the core toolset.
