   Hi all,   
      
   I'm investigating whether rules engines would solve a problem within   
   my company. We're a large financial institute, and the existing rules   
   are hard-coded bits of C and assembler (nice) compiled and run on a   
   IBM mainframe.   
      
   Biggest problem for us obviously is the time taken to   
   update/change/modify rules - currently weeks/months. Now, we are   
   currently looking to migrate a large chunk of or core processing   
   systems, but without affecting the performance (peak processing of   
   approx 7000 transactions per second, with an estimated rule base of   
   1500 - we're still investigating the complexity of the rules (depth,   
   rule-fire ratio, etc).   
      
   We're looking at existing systems vs developing our own solution, and   
   was wondering if anyone had any suggestion on products that could   
   perform.   
      
   Given that the data is constantly changing and the partial rule   
   matching will be low, will the rete alogorithm  (for example) be   
   redundant in our case? Any suggestions on alternative   
   approaches/products?   
      
   Cheers,   
   Elpico.
