<div>Hi,</div>
<div> I am asking about this code</div>
<div> "We already have code that converts the RuleModel object graph into DRL. However the object model is not tided to a database schema but you could write a layer that maps database tables to these objects" </div>
<div> </div>
<div>can u please let me know</div>
<div> </div>
<div>Thanks<br><br></div>

<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: rgb(204,204,204) 1px solid">(1) If you are looking for something simple my advice would be to define a database schema that can record your type of query:
<div><br><br>
<div>(Company=CCC && Organisation=OOO and Dept=HR) OR (Country=UK)</div></div>
<div>
<div>(Company=CCC && Organisation=OOO )and (Dept=HR OR Country=UK)<br><br></div>e.g. <br>COMPARISON_ELEMENTS_TABLE = Field, Operator, Value<br>COMPARISONS_TABLE = OpenBracket, COMPARISON_ELEMENT_ID, Connector, CloseBracket<br>
<br>Then write Java code that can convert this into a DRL string that is then handled the normal way.<br></div><br>(2) Firstly, I got the class name wrong. It should be org.drools.ide.common.client.modeldriven.brl.RuleModel.<br>
<br>We already have code that converts the RuleModel object graph into DRL. However the object model is not tided to a database schema but you could write a layer that maps database tables to these objects.<br><br>This would be quite complex but I include here to explain what I was trying to say.

<div>Hi,</div>
<div> Thanks for the reply.</div>
<div>But i can i get some more idea how to implement this.</div>
<div> </div>
<div>I dont understand the "You could also look at writing a persistence layer over FactModel which is the foregoing object model; to re-hydrate direct from structured database tables with an ORM."</div>
<div> </div>
<div>Can you please guide me something simple.</div>
<div> </div>
<div>Thanks,</div>

<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: rgb(204,204,204) 1px solid">The easiest suggestion would be to store DRL in your database ;)<br><br>These is a (dieing) BRL XML format but I believe its use is discouraged (as it's essentially an XStream output of a object model).<br>
<br>You could also look at writing a persistence layer over FactModel which is the foregoing object model; to re-hydrate direct from structured database tables with an ORM.<br><br>Looking however at your example rules; I believe the simplest approach would be to write your own parser that generates DRL.<br>
<br>Have you considered Guvnor which would suit your needs ideally?<br><br>With kind regards,<br><br>Mike<br><br>
