Abstract
The primary Department of Defense source for technical parametric performance data on non-communications emitters is the Electronic Warfare Reprogramming Database (EWIRDB). Data representation in the EWIRDB is via disjointed parametric tree models which are implementation oriented. These parametric trees obscure the intended semantics and representation of the data, making the database difficult to use and understand. The problem addressed by this thesis is to determine if the relational model and the relational interface of the Multimodel and Multilingual Database System (M2DBMS) in the Laboratory for Database Systems Research at the Naval Postgraduate School is capable of supporting a representative subset of the EWIRDB. We implemented a representative portion of the EWIR database on the relational interface of the M2DEMS. In order to accomplish this the relational interface was reactivated and returned to its original operational state and fully tested to determine its capabilities. In addition, the schema and an instance of a relational EWIR data model must be developed for implementation. The relational interface was successfully returned to its original operational state. Significant limitations in the interface's ability to process queries were discovered, however, in that the system can not query schema of greater than four relations.
