I would comment that Access often gets high marks for end-user
usability in comparative reviews. IMNSHO, it is simple if you limit
yourself to simple, end-user functions. But, of course, you soon will
want to do more, and the learning curve is not steep to improve your
skills to power user or even developer level. And you can make those
moves without ever abandoning Access, even to the point of creating
client applications to server databases, such as MS SQL Server,
Informix, Oracle, and others.
