Abstract

Abstract Many users of handheld computing devices or "palmtops" also own personal computers (PCs) 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 PC. A method and apparatus reconciles records on a palmtop with corresponding records on a PC.

Claim 9
Independent Claim 311 words
A method for reconciling a first file, a second file corresponding to said first file, and a backup file, said backup file containing records from a previous reconciliation, said method comprising: copying a first record from said first file into a reconcile file when said first record is added to said first file, and said first record is not in said backup file; copying a second record from said first file into said reconcile file when an identical said second record is added to said first file and said corresponding second file, and said second record is not in said backup file; copying a third record in said first file into said reconcile file when said third record is modified in said first file and a corresponding third record is deleted from said second file, and said third record in said first file is not in said backup file; copying a fourth record from said first file into said reconcile file when said fourth record is modified in said first file, and said fourth record is not in said backup file; copying a fifth record from said first file into said reconcile file when said fifth record in said first file is modified and an identical modification is made to a corresponding fifth record in said second file, and said fifth record in said first file and said corresponding fifth record in said second file are not in said backup file; and copying a sixth record from said first file and a corresponding sixth record from said second file into said reconcile file when said sixth record in said first file is modified and a different modification is made to said corresponding sixth record in said second file, and said sixth record in said first file and said corresponding sixth record in said second file are not in said backup file.
