help on reporting requirement

I'm new to Pentaho. We have a data warehouse which we want to extract the data out for reporting purpose. The data on the data warehouse is de-normalized data stored in as flat tables.

What we want to do is to extract ad hoc report on demand or recurring (if recurring, it has to be automated, say monthly). Is pentaho the right tool to accomplish this task? Any other suggestion?

At this point, we're not interested in anything beyond the requirements above but don't mind to keep the option open.

Thanks.
