Technical assets are representations of data elements, technical data sets, data containers that Metadata Command Center extracts from a source system.
The technical assets that you see in Data Governance and Catalog depend on the configurations that your organization administrator applies in Metadata Command Center. These configurations include the metadata extraction settings for the catalog sources, the capabilities that are enabled, the profiling filters that are applied, the job schedules that are defined, and other factors. For more information about catalog source configurations, see Administration in the Metadata Command Center help.
Technical assets in Data Governance and Catalog can be broadly categorized in the following manner:
•Data elements are the smallest unit of data in a source system. Columns, files, fields are examples of data elements.
•Technical data sets are a collection of data elements. For example, a table is a technical data set as it is a collection of columns.
•Data containers hold the data for an application. Examples of data containers are schema and database.
•Catalog sources are objects that represent the source system from which you extract metadata. You can create catalog sources in Metadata Command Center to extract metadata from source systems like Amazon S3 and Oracle.

Creating data sets from technical assets
Create a data set from a technical asset, such as a table, to establish an automatic relationship between them. When you create a data set from a technical asset, you add business context and meaning to the technical asset. You can assign stakeholders to the data set, relate the data set to other assets, and view the data elements related to the data set.
1Open the technical asset for which you want to create a data set.
2On the Overview tab, click Create Data Set.
3On the New Data Set page, enter the following properties of the data set that you want to create:
Field
Description
Name
Name of the data set.
System
Select the name of the parent system asset to which the data set belongs.
Description
Description that adds meaning or context to the data set.
Reference ID
Unique identifier for the data set.
The data elements associated with the technical asset are displayed on the Data Elements section of the New Data Set page.
4Click Create to create the data set.
When you open the data set asset page, you see different tabs on the page. For more information about what each tab on the data set asset page means, see the Understanding Business Assets help.
Creating system assets from technical assets
Create a system asset from a catalog source to establish an automatic relationship between them. When you create a system from a catalog source, you add business context and meaning to the data contained in the catalog source. You can assign stakeholders to the system, relate the system to other assets, and more.
