Summary of Data Modeling Rules

You can verify these rules automatically, for selected model objects or for a whole model, by running Consistency Check. In addition, the Consistency Check software points out a number of the suspect conditions that are mentioned earlier. Those situations that must be addressed before the analysis model can be considered complete are flagged as errors. Any questionable situations with no definite errors are flagged as warnings.

CA Gen enforces some rules automatically and does not permit data modeling objects that contain errors to be used for system design or in the Data Structure Diagram. See the chapter "Block Mode Design" and the chapter "Client/Server Design" for more information.
