Data Lineage Enhancements

Data Lineage Enhancements

Effective in version 10.0, data lineage diagrams have the following enhancements:
Summary lineage for PowerCenter mappings
When you view a data lineage diagram that includes a PowerCenter mapping, Metadata Manager displays a summarized view of the mapping by default. The summary view displays mapping inputs and outputs in the data lineage diagram but hides the transformation logic. The summary view reduces the complexity of the data lineage diagram. It also reduces the amount of time it takes for Metadata Manager to generate the data lineage diagram.
To view all of the transformation logic in a mapping, click
Switch to Detail
on the data lineage diagram toolbar. The following image shows the
Switch to Detail
The "Switch to Detail" button appears on the left side of the data lineage diagram toolbar.
To switch from the detail view to back to the summary view, refresh the diagram.
Filter objects
You can filter the objects that appear in a data lineage diagram. You can filter individual objects or all objects of a particular class. For example, you might want to remove all business terms from a data lineage diagram. You can remove any filter that you apply.
Improved performance
Metadata Manager uses a file-based graph database for storing and retrieving data lineage linking information. As a result, Metadata Manager generates data lineage diagrams more quickly than it did in previous versions.
When you upgrade to version 10.0, the upgrade process creates the graph database and copies data lineage linking information from the Metadata Manager repository to the graph database. You can configure the location that Metadata Manager uses to store the graph database files.
Cancel creation of a diagram
If Metadata Manager takes a long time to generate a data lineage diagram, you can cancel creation of the diagram.
For more information about data lineage diagrams, see the "Working with Data Lineage" chapter in the
Informatica 10.0 Metadata Manager User Guide
. For more information about configuring the Metadata Manager lineage graph location, see the "Metadata Manager Service" chapter in the
Informatica 10.0 Application Service Guide
