MaxCompute projects and databases are engine instances bound to a DataWorks workspace. MaxCompute projects handle computing, while databases come from engines such as MySQL, PostgreSQL, Hologres, DLF, and E-MapReduce Hive. Their metadata detail pages in Data Map share a consistent structure, with minor differences described below.
Access project or database details
You can open the detail page for a MaxCompute project or database in any of the following ways:
-
Drill down from a workspace: On the View workspace information page, click the name of the target MaxCompute project or database in the Project/Database list on the right.
-
Access through metadata retrieval: In metadata retrieval, set the metadata type to the appropriate project or database type, and then click the target object in the search results.
-
Access from the Data Catalog: In the navigation tree on the left side of the Data Catalog, expand the MaxCompute data source and select the target project node, or expand an engine data source and select the target database node.
Common page layout
The detail pages for MaxCompute projects and databases share a similar structure with the following common sections:
-
Basic Information: Shows key fields such as the asset name, type, associated DataWorks workspace, owner, creation time, and description. This section also provides the entity ID (GUID), which you can copy for integration and programmatic use.
-
Drill-down table list: Lists all tables in the current project or database, with search by table name. Each row provides actions such as Favorite and Request Permissions. Click a table name to view details such as columns, lineage, and usage records. If you have the required permissions for Data Collections, you can also select multiple tables and click Add to Album to add them to a Data Collection in bulk.
-
Custom Properties: If an administrator has configured custom properties for project or database entities, the detail page shows the corresponding property cards. Custom properties can be inherited from the workspace. For more information, see Custom Properties.
MaxCompute project-specific content
Beyond the common layout, a MaxCompute project detail page includes the following additional information:
-
Top Statistics: Shows the Total Tables, High-quality Tables, and Members counts, giving you a quick overview of the project's scale and asset quality.
-
Project-specific fields: The Basic Information section additionally displays fields such as Project Type (lakehouse projects are marked with a corresponding label), Environment, Lifecycle, and Compute Resource.
-
Technical Information: Shows fields such as Business Department and Business Owner. This section is visible only if you have permission to view technical information.
If the current project is a lakehouse project, the API Generation and DataAnalysis buttons on the table detail pages drilled down from this project are disabled.
Database-specific content
Data Map provides a unified database detail page for various data sources bound to DataWorks, such as MySQL, PostgreSQL, Hologres, DLF, and E-MapReduce Hive. Beyond the common layout, the page shows differentiated fields based on the database type:
-
Database type and Catalog: The Basic Information section indicates the engine type and displays associated catalog information (such as DLF Catalog or Hive Catalog).
-
Entity ID help documentation: The page header links to help documentation for the entity ID, explaining how to use it for this type of database.
The metadata fields, visible columns, and available row-level actions may vary depending on the database type. Refer to the actual page for details.
