Is MS Access (JET) suitable for multiuser access?

阅读更多关于 Is MS Access (JET) suitable for multiuser access?

I have a product designed to be a desktop product using MS Access file as a DB. Now, some users need to install it in a few PCs (let's say 2 or 3) and SHARE the database.

问题 Google has just released Android 4.2, which includes support for multiple user profiles on a single device: http://developer.android.com/about/versions/android-4.2.html#MultipleUsers.
