I'm glad you posted the link; I'm wondering if you are able to read and understand what you post and base your opinions on... read on I have copied some info from your link:
"The larger vendors — Microsoft, Oracle, SAP, Business Objects — cannot even measure their OLAP business themselves, because their OLAP capabilities are often delivered as part of larger, bundled products. For example, Microsoft Analysis Services and the OLAP capabilities of SAP BW are not sold separately, but are included as part of product suites. "
-first point - difficult to measure because of a bundling of services... I guess analysis services comes with every version of SQL Server sold, whether they use it or not is another question... this skews the results... cause it is probably not being used... why? read on... (from your link again)
"Microsoft had its third consecutive year with no new OLAP product releases, though many of its partners delivered improved front-end tools which increased the attraction of the Microsoft OLAP platform. This meant that Microsoft continued to grow faster than the market, though at a slower rate than previously. Much the same is expected in 2004, with Microsoft again relying on its partners for product enhancements, with the major ‘Yukon’ release of SQL Server delayed into 2005 and Microsoft’s own weak OLAP front-end capabilities also not expected to be significantly upgraded during 2004."
So microsoft ain't doing anything.. no revision no nothing... probably cause many people are not using the featurs of analysis services so there is no need to upgrade.. hence false measurement in terms of OLAP market share... it's bundled in with the DB that people use; not anaysis services...
As far as the rest of the players go:
"The large non-specialist vendors, such as Microsoft and Oracle, are stronger in the rest of the world than the smaller BI specialists, who tend to be UNDER-REPRESENTED outside the major markets. By vertical market, MicroStrategy is particularly strong in retail, Applix in finance and insurance and Microsoft and Business Objects in the IT industry."
Again, the above is from your link; so it's important to see who is gaining market share... market share isn't gained by a product being sold in a bundle... it's gained by a product being used!!!
I hope you can see my point; once again the microsoft marketing machine out to prove to the world that it is gaining market share... maybe... but nobody uses their product; in this specific case - Analysis services... packaged with a bundle doesn't mean it's gaining market share... I've worked in many IT shops where they use SQL server and avoid analysis services cause it's a weak offering...
what do you have to say to that?
