Entity-Relationship Approach to Navy Command and Control Conceptual Data Modeling for Decision Support

摘要

The Fleet Command Center Battle Management Program (FCCBMP) is an advanced technology prototyping effort introducing Expert System technology (e.g., rule based systems, artificial intelligence) into the Command Center of the Commander in Chief, U.S. Pacific Fleet. This paper discusses the application of advanced data base design methodology to an existing database supporting Expert Systems to ensure data consistency. The objectives of the task were to: (1) identify problem areas, (2) develop a conceptual model, (3) demonstrate the conceptual model using the FCCBMP database system, and (4) propose related research areas for further investigation. Problem areas identified included: (1) lack of a well-structured design, (2) data requirements and consistency constraints were not well specified, and (3) the DBMS has difficult in enforcing data integrity and consistency. The Entity-Relationship model was successfully used to develop the conceptual model. Data abstractions proposed in other models were incorporated into the conceptual model as required.
