In short, no it doesn't. You'd treat the DRL text as a CLOB or something similar with schema to suit your application requirements.<br><br>You could use Guvnor to store your rules and configure this to use Oracle, although the table structure would not be specific to Drools as Guvnor uses JCR internally. Guvnor offers versioning of rules.<br>
<br>There is a REST API to integrate your application with Guvnor.<br><br>With kind regards,<br><br>Mike<br><br><div class="gmail_quote">2011/7/13 Vineet Arora <span dir="ltr"><<a href="mailto:Vineet.Arora@hcl.com">Vineet.Arora@hcl.com</a>></span><br>

I assume that you know how to store entire rules or bits and pieces as
"text" in some DB, and how to retrieve them and compose them into rules
according to your requirements. <br>
<br>
If "configuration" is just the repeated insertion of values (or
larger chunks of text) into rules, you could look at "templates" and
how to generate rules via the Drools API.<u></u><u></u></p>

Once you have a String aDrlString containing text as you would normally have it
on a file, you can<br>
- write it to a file and compile that<br>
- pass the String aDrlString to the builder by:<br>
Resource res =
ResourceFactory.newReaderResource( myStringReader );<br>
kBuilder.add( res,
ResourceType.DRL );<br>
