Database management system (DBMS) support for expert system knowledge bases requires data-modeling tools matching system needs. To assess its power and fit for this application, the authors applied their logical data structures data-modeling tool, LDS, to an existing rule-based expert system, Galen, and produced a clear logical schema, comprehensible by its producers and other audiences. They believe that this technique could help the design of novel systems and that its use on existing systems will facilitate DBMS support. >
