The Entity-Relationship approach is investigated to
determine its suitability for the construction of a logical
database design for a tactical data system (TDS) to be used
by surface ships in the U.S. Navy. Some motivation for the
use of database techniques in the design of a TDS is given,
and a conceptual schema design baaed on the Entity-Relationship
approach is presented. This design includes Entity-
Relationship diagrams in some detail for major entity and
relationship sets for a TDS. An attempt to model behavior
using Petri nets is described and several developed Petri
nets are shown. It is concluded that the Entity-Relationship
approach is workable for the task of building a TDS
logical database design and that the resulting design is
expressive and flexible. It is also argued that the simplicity
of the Entity-Relationship model makes design validation
by real-world domain experts easier.
