OpenEdge SQL supports Change Data Capture(CDC), and implementations of CDC which can involve Extraction/Transformation/Load(ETL) applications that extract individual data changes for each table. Instead of dealing with the entire table, OpenEdge customers can selectively choose fields from an individual table to capture data and populate it to an external data source. This approach avoids replicating the entire database or an entire table, and provides scalability to the process. OpenEdge CDC is a scalable solution as it allows the CDC policy designer to determine the amount of data change detail needed.
