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. Support for Attributes, Elements, Structures, and Domains New grids provide extreme ease of use for modeling attributes of entities. Now, however, you drag data into the attribute grid, where you can 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.
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. Also, once you have completed your logical model, you can run a series of rules checking and normalization reports to validate the integrity of your design. System Architect tests for First, Second, Third, and Boyce-Codd Normal Forms.
