We are embarking on a big project which has a quite few number of mandated reports to be produced in batch. We are using Business Objects ( crystal enterprise ) for all our online/adhoc reporting needs. It is a J2EE application. We are in the process of deciding which reporting tool we should use for Batch. I tried to look it up on the web; all the posts regarding comparisons are really old and I do not whether it is relevant any more or not. My main issue is performance; how BO fares with Oracle Reports. I heard BO does the joins on the client side; my knowledge in BO is very limited. On the other there is a pressure to keep the whole reporting environment uniform ( BO every where ). My main concern as a DBA is performance; I do not want to end up with a product which inherently has performance limitations. Any comments, pointers or white papers are of great help.
