Introduction to IBM Db2 for LUW Script catalog sources
You can use Metadata Command Center to extract metadata from a source system.
A source system is any system that contains data or metadata. For example, IBM Db2 for LUW is a source system from which you can extract metadata through an IBM Db2 for LUW Script catalog source with Metadata Command Center. A catalog source is an object that represents and contains metadata from the source system.
Before you extract metadata from a source system, you first create and register a catalog source that represents the source system.
When Metadata Command Center extracts metadata, Data Governance and Catalog displays the extracted metadata and its attributes as technical assets. You can then perform tasks such as analyzing the assets, viewing lineage, and creating links between those assets and their business context.
The following table describes the capabilities of the catalog source:
Capability
Description
Advanced Programming Language Parsing
Advanced Programming Language Parsing parses the source system code in addition to extracting objects from the source system.
Lineage Discovery
Builds the complete lineage of a catalog source by recommending endpoint catalog source objects to assign to reference catalog source connections. When you run the catalog source job, Metadata Command Center assigns the reference catalog source connections to CLAIRE recommended endpoint catalog source objects. You can then view the list of CLAIRE recommendations and accept or reject them.
