  21. 21. The Concepts 21
  22. 22. JBoss BRMS What is inferencing? ● 22 We want to take all of our data (facts) and combine it with our knowledge (rules) and come up with some conclusions (inferencing)
  23. 23. JBoss BRMS What is inferencing? ● 23 We want to take all of our data (facts) and combine it with our knowledge (rules) and come up with some conclusions (inferencing)
  24. 24. JBoss BRMS What is inferencing? ● 24 We want to take all of our data (facts) and combine it with our knowledge (rules) and come up with some conclusions (inferencing)
  25. 25. JBoss BRMS What is inferencing? ● 25 We want to take all of our data (facts) and combine it with our knowledge (rules) and come up with some conclusions (inferencing)
  26. 26. JBoss BRMS What is inferencing? ● 26 We want to take all of our data (facts) and combine it with our knowledge (rules) and come up with some conclusions (inferencing)
  27. 27. JBoss BRMS What is a rule? ● ● ● ● 27 In short, a rule is an premise and conclusion – If it is raining, then the ground must be wet A rule is made of conditions and actions. When all the conditions are met, a rule may “fire”. The conditions are collectively referred to as the LHS (left hand side) and the actions are referred to as the RHS (right hand side, or consequence). A rule operates on facts (data). In our case, these facts are instances of objects in our application.
  28. 28. JBoss BRMS Inference Engine ● ● ● 28 The brain of a Production Rule System is an Inference Engine which matches facts against Production Rules. When matches are found, the rules actions are fired. Actions most often change the state of the facts, or perform some external action on the application.
