Yes.

If the data "defines" the rules then there are numerous options:-
Construct a DRL String yourself and pass this to a KnowledgeBuilder

Use the fluent API to build rules programmatically

Construct an XLS decision table using your favourite XLS (Java) API and look at drools-decisiontables
Construct a Guvnor decision table using classes in droolsjbpm-ide-common (bundled with Guvnor)
If the data is to be plugged into place-holders in statically defined rules:-

Look at the use of Drools Expert Templates
Decision tables do not lend themselves well to "OR" as there is an implicit "AND" between columns.

There might be other solutions, these are those that came readily to mind.

With kind regards,

Mike

If it is possible to create a drl file or decision table dynamically in drool
or java?
Like the drool received data then create drl or decision table based on the
data?
Data: Condition 1 AND Condition 2 OR Condition 3 .....
Can the above data be stored in the rule file which also contains the
operators "AND", "OR"?
