Comparing Data Lineage and Data Propagation
Data Lineage and Data Propagation have these key distinctions:
- Propagation relates to field expansion (that is, a ripple effect of table column expansion). It encompasses:
- All directions
- All statements

Results should be the same no matter which field is used to start the operation.
- Lineage relates to field route (that is, a table columns origin and movement). It encompasses:
- One direction (forward or backward)
- Optional statements (usually pertinent only to transformation)
- Context sensitive

Results differ depending on seed and direction.
