title: Building inference engine to extract appropriate file from database
body: <p>I am working on numerical simulation software having a "reader" to exploit one simulation file.
  According to user input and other parameters, i have to extract the appropriate simulation file from database and send it to the client.</p>
  
  <ul>
  <li>1- is it appropriate to implement inference engine in my case ?</li>
  <li>2- What is the most appropriate language/inference engine should i use ? I was looking on Java+Groovy and for drools.</li>
