Data Catalogs

You can use data catalogs to search for and filter data assets; view asset details, lineages, and relationships; and add asset classifications and tags.

Searching for a Data Asset

An asset can be searched by its name, description, or attributes. Fuzzy search is supported.

On the DataArts Studio console, locate an instance and click Access. On the displayed page, locate a workspace and click DataArts Catalog.

Choose Data Map > Catalog from the left navigation bar.
Enter a keyword in the search box, and search for assets. The search results are listed below the search box. You can search for assets in either of the following ways:
- By their names and description
- By their attributes, which are displayed on the asset details page
  - You can save the search criteria you set.
  - You can import the search criteria you need.

Filtering an Asset

Assets can be filtered by the following criteria:

Data connection: the data connection that your target asset uses.
Type: the type of your target asset.
Classification: the category that your asset is classified into.
Tag: the tag that your asset includes.
Security level: the security level of your target asset.

The following uses type as an example to demonstrate how to filter an asset.

Select Table under Types. Table assets are displayed.
In the Types area, Table, Column, Database, Bucket, and ColumnFamily are supported by default. If you select All, the system displays assets of all types.

Viewing the Details of an Asset

The following uses a table as an example to demonstrate how to view the details of an asset.

In the list of searched assets, select a table and click its name to access its details page.
On the Details tab page, view the basic attributes of the technical metadata; edit the description; add or delete classifications, tags, and security levels for the table, table columns, or OBS objects.

Figure 1 Details tab page
On the Column Attributes tab page, view the column attributes of the table; add or delete classifications, tags, and security levels for the data columns; edit the description.

Figure 2 Managing column attributes
On the Lineage tab page, view table lineages and impacts. For details on how to set a data lineage, see Node Lineages. After the lineage is set for a node, the node can be automatically parsed during job execution. Then, the metadata is collected during data asset collection and is displayed on the DataArts Catalog page.
On the Summary tab page, view the summary of the data table. Currently, only DWS and DLI data tables can be viewed.

Click Update to update the table profile.
On the Data Preview tab page, view the effect after data is masked.
On the Change History tab page, view the change history of the table.
