Compare and Synchronize Oracle Databases with DTM Data Comparer

With DTM Data Comparer software any DBA or database developer can compare or even synchronize Oracle databases in a visual manner. The program uses fast and reliable Oracle Call Interface to access databases as well as traditional ODBC and OLE DB connections.

The program scans the contents of tables to be compared basing on the order of ascending of primary key or user defined unique key values. If the program can't find two data rows with the same key value, it places the records to different lines and highlights by the yellow background. In case values of the keys coincide, the program places them to the same lines and highlights equal fields in green and different fields in red.

The user can compare tables with different structure with column mapping feature. Also, the program allows the user to apply built-in Oracle functions to target database during data synchronization. It helps to make some kind of data conversion if necessary.
