    DataWorks:Manage data

    Last Updated:Jul 03, 2025

    After you perform user profile analysis, five data tables are created in MaxCompute, E-MapReduce (EMR), or StarRocks. You can view the created data tables in Data Map. You can refer to View lineages to view the relationships between the created data tables.

    Prerequisites

    Data is synchronized and processed before you perform operations in this experiment.

    Data source type

    Whether to manually collect data

    Prerequisite

    MaxCompute

    No

    Simple user profile analysis by using DataWorks and MaxCompute is complete.

    EMR

    No

    Simple user profile analysis by using DataWorks and EMR is complete.

    StarRocks

    Yes

    Simple user profile analysis by using DataWorks and StarRocks is complete.

    Note

    After user profile analysis is performed, five data tables are created in MaxCompute, EMR, or StarRocks. The data tables can be queried in the related data source.

    Go to Data Map

    In this example, the metadata collection feature of Data Map is used to collect metadata from various types of data sources.

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

    Step 1: Collect metadata

    1. In the left-side navigation pane of the DataMap page, click Collect Metadata. On the page that appears, find StarRocks on the Data Source Perspective tab and click Manage in the upper-right corner.

    2. Click the Data Sources for Which No Crawler Is Created tab. Find the desired data source and click Create Crawler in the Actions column.

    3. In the Configure Collection Plan dialog box, configure the Resource Group Name parameter and click Test Network Connectivity to test the network connectivity. After the test is successful, configure the Collection Plan parameter and click Confirmation.

      Note

      • For more information about metadata collection, see Metadata collection.

      • We recommend that you select a serverless resource group or an exclusive resource group for scheduling.

      • For a resource group that is purchased before February 1, 2024, if a network connection is established between the resource group and the data source but the network connectivity test fails, contact technical support to upgrade the resource group. Then, test the network connectivity again.

    Step 2: View the details of a table

    After metadata collection is complete, you can search for a table that is created during the user profile analysis process to view the table details.

    1. Search for a table.

      1. Log on to the DataWorks console. In the top navigation bar, select the desired region. In the left-side navigation pane, choose Data Catalog > Data Map. On the page that appears, click Go to Data Map.

      2. In the left-side navigation pane of the DataMap page, click the image icon. On the page that appears, select StarRocks on the Data Source tab, and then search for tables by type in the upper part of the page.image

        Note

        For more information about table search, see Query and manage common data.

    2. View the details of the table.

      After you find the desired table, click the table name to go to the table details page. The table details page displays the following information of the table: basic information, technical information, business information, details, and usage notes. For more information, see View the details of a table.
