Could someone explain the differences between Relational DBMS and Expert Systems. I would like to know the kinds of things that cannot be done with RDBMS for which you need Expert Systems Technology. When I look at most of the Expert System Shells they provide a syntax for representing the domain specific data (or knowledge) and a way to use the data (conditional knowledge or inference mechanism). Can't the same thing be achieved with tables and queries in a RDBMS. Is the chaining through conditional knowledge possible in ES is missing in RDBMS? I always have trouble in explaining the differences between the two when someone asks. I have heard people saying relational algebra cannot do recursion (I don't know what this means). I would appreciate any clarification on this from the netters. Thanks. -- ravi skumar@hocus.att.com
