For managing personal information on the iPad, it’s hard to beat Bento, a database application targeted at consumers and single-handed businesses. Heavy-duty data crunchers, though, have a different set of needs, not the least of which is working with databases created by Bento’s big brother, FileMaker Pro. To meet those needs, FileMaker, a wholly owned subsidiary of Apple, has introduced FileMaker Go for the iPhone and iPod touch, as well as the iPad. It allows users of those machines to work on databases created with FileMaker on those devices.
