Rule Based System Architecture
   
 
   - This is the runtime architecture
 
   - The user starts the system and interacts with it via the user 
       interface. 
 
   - This is the command prompt in Clips.
 
   - The engine is the part of the program that actually does stuff.
 
   - It says, run the system, that is, look at working memory, see 
       what rules fire, and apply them.  
 
   - You'll have the same inference engine for each rule base.
 
   - The knowledge base is the rules and the working memory.
 
   - The rules will remain the same for different runs.
 
   - WM changes for each run and during the run.
