BRE with database

Hello,

I have a question about the business rule engine.  The problem is this:  I want to use the BRE to look up data from a database and if some condition is true it the data gets updated.

But when executing the rule it never gets updated in the database.

So my question is this, what is the good way to access data from a database in the BRE.  Is it just enought to drag the columns from the Fact explorer in the rule page or do I need to write .net code to retreive the data?
