To extract metadata from a source system, configure the catalog source and run the catalog source job in Metadata Command Center. Then view the results in Data Governance and Catalog.
The following image shows the process to extract metadata from a source system:
After you verify prerequisites, perform the following tasks to extract metadata from Teradata Database:
1Register a catalog source. Create a catalog source object, select Teradata Database, and then select and test the connection.
2Configure the catalog source. Specify the runtime environment and configure parameters for metadata extraction. Optionally, add filters to include or exclude source system assets from metadata extraction. You can also configure other capabilities such as data profiling and quality, data classification, or glossary association.
3Optionally, associate stakeholders. Associate users with technical assets, giving the users permission to perform actions determined by their roles.
4Run or schedule the catalog source job.
5Optionally, if the catalog source job generates referenced asset objects, you can assign a connection to referenced source system assets.
You can view the lineage with object references without performing connection assignment. After connection assignment, you can view the objects.
After you run the catalog source job, you view the results in Data Governance and Catalog.
