摘要

An object-oriented Structured Entity Method (SEM) design and maintenancemethodology was completed as partial fulfillment of the February 3, 1989 proposal. Due to the object-oriented nature, the methodology has been renamed the Structured Object Methodology (SOM). SOM provides high level design tools somewhat similar to Entity Relationship Diagrams that, unlike ER Diagrams, are top down and hierarchical. SOM diagrams translate easily into objects that can be coded into a knowledge base. The resulting knowledge base is easier to understand and maintain than conventional knowledge bases with no underlying organization to their rules. As was also suggested in the February 3, 1989 proposal, a prototype of an integrated KB/DB for the IOIS was completed. The prototype fully utilizes SOM and verifies that it is a reasonable design technique. SOM proved to be better suited to the task of integrating a KB/DB than other design techniques that were explored at the same time. A subset of AIRMICS data was modeled using SOM and then entered into a normalized database. Oracle was chosen for the DBMS and the knowledge base was written using PC-Scheme/Scoops, an object-oriented dialect of LISP.
