Data Lineage
Trace data from DB2 columns and file fields through COBOL host variables across programs and copybooks in OL AtomIQ.
Data Lineage in OL AtomIQ traces how data moves from database columns, IMS segments, and file layouts through COBOL host variables and across programs and copybooks.
Capabilities
- Interactive lineage tree with source-context preview
- Direction-aware usages (read vs write paths)
- Entry from DB2 Table Metadata (Track field lineage) and related resource views
- Cross-program and copybook tracking for impact analysis
- IMS-DC COBOL flavor: DL/I segment fields and CBLTDLI I/O areas participate in the same lineage walk
Typical workflow
- Open a TABLE resource → table metadata
