A family of Microsoft relational database management systems designed for ease of use.
When a company ignores its MVPs (and there are several pitching in on this one) then we know we are in serious trouble and the implications that has for the substantial investments we have made in that company's products. We now know we were mistaken to invest in Access all those years ago but all was ok up to about 1 year ago. People who suggest moving the backend over to another product have no idea the amount of work that entails for a mature product that has been deployed for over 10 years with no stability issues until recently.
The solution here is that Microsoft start taking this seriously and locate the fault. I am sure there are many developers out there who are having the same problems.
