You can't compare an OLAP server like MS Analysis Services with client
tools like Crystal Analysis Professional. Now that Holos is dead,
BO/Crystal doesn't have an OLAP server, and Microsoft doesn't currently
offer a serious OLAP front-end. However, MS Reporting Services (MRS) can
be used to produce static formatted reports from Analysis Services, just
as Crystal Reports can. Neither is great at the job, but at least MRS
comes free with the server.
And among the many available client tools for Analysis Services, Crystal
Analysis Professional is far from the best, and it's perhaps surprising
that Business Objects has chosen this rather than WebI OLAP as its
preferred client tool for accessing OLAP servers. In essence, both
Business Objects and Crystal were relatively weak at accessing OLAP
servers anyway, and putting them together isn't likely to improve things
in this area any time soon.
As an aside, I don't think that Business Objects regards relational
queries as something less important than OLAP. They probably would think
of Crystal Analysis Professional as being relegated to the OLAP task,
with WebI freed to concentrate on interactive relational reporting.
