A family of Microsoft relational database management systems designed for ease of use.
Not sure what the issue is. You can build a form using Access that was designed for the 8" tablet. The issue is that trying to enter data on an 8" tablet with an onscreen keyboard is different from entering data on a larger tablet which is different from entering data on a laptop or with a full external keyboard.
This is true of an iPad or Android or Win 8 tablet.
