Data Lineage
Trace data from DB2 columns, IMS segments, and file fields through COBOL host variables across programs and copybooks.
Before you decouple a program or design an API around a table, you need to know where each field goes. Data Lineage answers that from the COBOL source. A change to a copybook or a table can then be checked against every program that reads or writes the field, instead of being found in production.
