    DataWorks:Data Catalog

    Last Updated:Jun 25, 2026

    The data catalog organizes the data assets visible to you in DataWorks, grouped by data source type. The left side shows a catalog tree, the right side shows the details for the selected node, helping you quickly browse engines, databases, tables and datasets, and perform actions such as creating a dataset or installing open data.

    Enter the data catalog

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

    2. In the left-side navigation pane, click Data Map, then click Data Catalog to open the data catalog page.

    Page layout

    The data catalog uses a two-pane layout:

    • Left catalog tree: Shows the assets you can access, grouped by data source type. On the public cloud, the tree shows the DataWorks Projects group by default, groups for each engine data source (such as MaxCompute, Hologres, DLF, Hive, MySQL), and DataSet. If your tenant has activated PAI, a PAI catalog group also appears; if you have activated Open Data, the Open Data Catalog group appears at the bottom of the tree.

      Note

      The data source types actually visible in the tree depend on the engines bound to your tenant and on the metadata that has already been collected. The visible scope may differ across tenants and workspaces.

    • Right details panel: Renders content based on the node selected in the left tree. Selecting a data source root node shows the engine overview; selecting a database or catalog shows the tables under it; selecting a table or dataset embeds the corresponding details page (the content is identical to the metadata details page).

    Common operations

    • Browse assets: Expand a data source, database, or catalog node in the left tree to drill into its tables and datasets. Clicking a table name or dataset name switches the right panel to the corresponding details.

    • Search the catalog: Use the search box at the top of the catalog tree to locate a target object by node name.

    • Create a dataset: Under Catalogs, click DataSet. After entering the dataset list for the workspace, click Create Dataset and follow the wizard to create datasets such as OSS or NAS datasets. For more information, see Manage datasets.

    • Use open data: When the Open Data Catalog group appears in the tree, you can browse and install available open datasets. For more information, see Manage open data.
