Metadata Dependencies and Lineage and Impact Analysis

OWB provides the Metadata Dependency Manager to detect and resolve the impact of the changes made to the object definitions or the metadata in the workspace. The Metadata Dependency Manager generates lineage and impact diagrams for any data object. A lineage diagram traces the data flows for an object back to the sources and displays all objects along those paths. An impact diagram identifies all the objects that are derived from selected object.

This type of information can help you in many circumstances as follows:

• Comply with government regulations or other audits that require tracking of financial data.

• Modify the system design because of changes in the source data.

• Modify the system design because of new requirements for reporting and analysis.

• Assess the impact of design changes in a pluggable mapping that is used throughout a project.
