The Database Comparer in Delphi (UniDAC) example was published on GitHub.
This Delphi project connects to an IB database via the UniDAC library, compares, synchronizes, and updates the database structure and table data.
The project represents a mostly simple demos and by no means, a complete application. It's intended to demonstrate how to use the DB Comparer component in your Delphi application. Additionally, the program uses the Table Data Comparer component to synchronize table records between two different databases.
