Last Updated:Jan 19, 2024

If you want to quickly find data, such as tables in a workspace or a data source, or code or APIs in DataAnalysis or DataService Studio, you can find the data in Data Map.

Go to the DataMap page

Log on to the DataWorks console. In the left-side navigation pane, choose Data Governance > Data Map. On the page that appears, click Go to Data Map.

Search for a table

In Data Map, you can quickly search for tables of the supported compute engine types and view the details of a table, such as the fields in the table and table lineages, on the table details page. You can also perform operations, such as requesting permissions on a table, adding a table to a data album, or analyzing data in a table.

Search for a table on the homepage of Data Map

In the left-side navigation pane of the DataMap page, click the image.png icon. The homepage of Data Map appears.

  • You can quickly search for the desired table of a specific compute engine type by entering a keyword in the search box on the homepage.

  • The homepage displays the most frequently viewed or read tables based on conditions, such as your browsing history and the popularity of the tables in the current Alibaba Cloud account. You can quickly click the desired table to view the details of the table.

  • After you find the desired table on the homepage and go to the details page of the table, you can view the basic and business information about the table. For example, you can view the project to which the table belongs, the table owner, and whether the table is in the production or development environment. You can also click each tab on the right of the details page to quickly view information such as the fields in the table, table lineages, and data preview results. This helps you understand the table schema and table content in an efficient manner.

The lineages that are generated by manual operations such as ad hoc queries are excluded. For more information, see the View lineage information section in this topic.

Precautions

  • You can view tables of only the following compute engine types:

    • MaxCompute: The query operations of different compute engine types are similar. If you want to use a MaxCompute compute engine, you can refer to MaxCompute table data to learn how to query tables and perform the related operations.
