A family of Microsoft relational database management systems designed for ease of use.
The only way it becomes a contradiction is if you don't read what I actually have said instead of what you want to think I said. That Access is a tool for a small business developer is undeniable. That doesn't mean that Microsoft planned it that way, Yes, Access was designed from the beginning to be an end user/small workgroup tool. That it has become what it has is mostly inadvertent, not planned.
And no, those things don't support your argument. Migration to SQL Server was improved with SSMA so the Upsizing wizard became unnecessary. Net Gain! Pivot tables are a net loss, but the ability to do Pivot tables was not taken away just moved. Granted it makes doing them more cumbersome, but its not a complete loss. As for the security feature, MS is moving away from Jet and towards SQL Server, has been for a while. ADPs were a flawed attempt at that, SQL Server clearly has a much more powerful security model. It was removed for the same reason other features were removed. MS has a limited amount of resources and has to prioritize what it can support. I don't understand how you can say that is not consistent with Access as a Developer platform. Doing so shows a lack of understanding of what Access is. The Jet engine is just one part of Access. It is actually it's weakest part. But the fact is that it is an interchangeable part. One can develop a full application in Access with UI, reporting and workflow processing and then plug in almost any database engine.
