Business Objects and Db Performance

I'm new to Business Objects, and I have a question to ask,

Does creating universe in the designer actually creates indexes in the DB? Or universe is just a reference model for the BO app.

If so, won't poor designed universe slow down DB performance?

For those who have experience in BO, please advise. Thanks.In my experience BO does not create any indexes in the DB. And yes, universe design is very important as poor universe design will lead to poor performance.. I am using BO 5.1.?, I'm not sure what version you are using.

Any more questions please let me know.

Thanks,
