Claim:
A method comprising: requesting, by a first computer, changes in current data records; receiving, from a first synchronization computer, changes from a previous export of data records from a difference unaware information repository, the changes from the previous export of data records being changes between a difference unaware current state of associated data records and the previous export of data records from the difference unaware information repository; receiving, from a second synchronization computer, changes from a previous export of data records stored in a difference aware information repository configured to track changes in data records for each data records entry within its own repository; mapping, by the first computer, the received changes from the previous export of data records from the difference unaware information repository and the received changes since the previous export of data records from the difference aware information repository to corresponding form fields in a master data records list to create an updated master data records list; saving, by the first computer, the updated master data records list; and forwarding, from the first computer to the second synchronization computer, the updated master data records list.
