Abstract
Abstract Many users of handheld computing devices or "palmtops" also own personal computers running applications that manage data similar to the data carried in the palmtops. In such cases, the users are likely to want the data on the palmtop to be synchronized with the data on the personal computer. A method and apparatus reconciles records on a palmtop with corresponding records on a personal computer.
