Does BIRT support snowflake schema?

We are currently using Cognos to create business reports. We have hit a wall in the requirement that the Cognos only supports star schemas, and not snowflake schemas.

Does BIRT support snowflake schemas?

You can formulate any SQL query you like in BIRT. Any snowflake schema can be queried using SQL. So, the answer is "yes".

Let me rephrase. Can a business user who is not familiar with SQL use BIRT against a snowflake schema?

PHeadlandCommented:
I don't think a business user who is not familiar with SQL can use BIRT for anything more than very trivial applications, since using BIRT requires designing queries. The exception to that would be if you use Actuate's commercial products built around BIRT, which include design tools and a meta-schema system that can hide the complexity of building queries.

Yes - you can use the Actuate Information Object Designer to create models that hide the complexity of the snowflake schema; these appear as a single table to the user and the Actuate Information Server creates the appropriate optimized SQL automatically based upon which columns are chosen, filter criteria, etc. If you are interested, you should get an Actuate rep to give you a demo.
