Introduction to Teradata MultiLoad 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, Teradata database is a source system from which you can extract metadata through a Teradata MultiLoad 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.
You can only extract metadata using this catalog source.

Extraction and view process

To extract metadata from a source system, configure the catalog source and run the extraction 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 script:
The image shows the process of metadata extraction from a source system that begins with prerequisites verification, continues with the creation of the catalog source, and ends with viewing the extraction results.
After you verify prerequisites, perform the following tasks to extract metadata from Teradata MultiLoad Script:
  1. 1Register a catalog source. Create a catalog source object, select Teradata MultiLoad Script, and specify values for connection properties.
  2. 2Configure the catalog source. Specify the runtime environment, configure the metadata extraction capability, and add filters.
  3. 3Optionally, associate stakeholders. Associate users with technical assets, giving the users permission to perform actions determined by their roles.
  4. 4Run or schedule the catalog source job.
  5. 5Assign a connection to referenced source system assets.

About the Teradata MultiLoad Script catalog source

You can use the Teradata MultiLoad Script catalog source to extract metadata from script files that define transformations on a Teradata database source system.
Teradata MultiLoad Script is a set of Teradata MultiLoad statements stored in a file that you can use to import data from input files, applications or other correctly formatted sources to a Teradata Database.

Compatible connectors

Before you configure the Teradata MultiLoad Script catalog source, you must connect to the Teradata database source system.
Use the Teradata connector to connect to the Teradata database source system. For information about configuring a connection, see Administration.

Extracted metadata

You can use the Teradata MultiLoad Script catalog source to extract metadata from the Teradata database source system.
Metadata Command Center extracts the following metadata from the Teradata database source system:

Input files

You can extract metadata from Teradata MultiLoad input files.
