The DataWeigher is the tool to compare and synchronize data of MS Access databases. You can select any tables and fields from two MS Access databases and DataWeigher finds differences. The comparison result is very visual, each type of records (added, deleted, changed) has its own color. You can save the detected changes as a report or SQL script to synchronize data.
