The Database Comparer ActiveX represents the com-based superstructure on the Database Comparer VCL edition. The main purpose of the Database Comparer library is to provide to the end-users the higher-level interface available in any languages with com-support routines, such as Visual Basic, Visual C++, VBScript, JavaScript and many others. Database Comparer helps you to compare, synchronize and update databases structure. You can compare one database with another database or database with DDL/SQL script or even two DDL/SQL scripts. Database Comparer implements highly intelligent and robust synchronization algorithm. During first comparison step it takes Target database or Target SQL/DDL script and compare it to the Master database or Master SQL/DDL script trying to locate all structure differences and prepare final SQL script which will be applied to the Target and make its structure equal to Master structure. At this stage Database Comparer extracts all objects, descriptions and links from both Master and Target structures and then compares actual objects from Master with objects from Target building final update SQL script. After final update SQL script is ready you can apply it to the Target database if it is available or just save it to the file and run it later. Database Comparer supports following servers: InterBase SQL server and it's clones - FireBird and Yaffil (Yaffil team recently announced merge with FireBird) SQL Anywhere. Borland InterBase Express components library (IBX) is used by default to work with InterBase / FireBird. Alternatively Database Comparer supports Fast InterBase Plus components by Devrace (FIBPlus) and Interbase Objects (IBO) library.
