    Por Que e Quando Desempenhar Esta Tarefa

    A data interface is a logical table that allows you to map to various data sources (external systems or ServiceNow tables) and query them uniformly, abstracting away the complexity of where data physically resides. Perfect for scenarios where you need flexible data access that can adapt as source systems change or when multiple sources need to be queried through a single, consistent interface.

    Procedimento

    1. Navigate to All > Workflow Data Fabric > Workflow Data Fabric Home.
    2. Select the Data Workbench icon(Data workbench icon).
    3. Select Create > Create Data Interface > Get started.
    4. Add basic details for the data interface under the Basic details tab.
      1. On the form, fill in the fields.
        Tabela 1. Basic details form
        Field Description
        Table name Name for the data interface.
        Unique name Auto-generated unique identifier which can be modified.
        Application scope Identifies the application files and data the data interface has access to.
      2. Select Continue.
    5. Select the source tables the data interface has access to under the Select source tables tab.
      1. Under Select source tables, and select Add.
      2. Opcional: Filter data assets or search for a source table using the search bar.
      3. Select a table to review its details, and select Add to add the source table.
      4. Repeat step 5c for all source tables you want to add to this data interface.
      5. Select Done, and review the added source tables.
      6. Select Continue.
    6. Select how to combine the data source tables under the Select combination method tab.
      The available combination methods are:
      Join
      Combine tables by matching rows that share the same key.
      Union
      Stack rows from similar tables to create one combined table.
      Single table
      Use all columns from one source table without combining data.
      Nota:
      There is no mapping step with a single table.
    7. Map columns from each data source to unify columns in the data interface under the Map columns tab.
      1. Select a Column name in the first data source represented by the first column.
      2. Select matching columns in all other data sources.
      3. Enter a Target column name for the unified data interface.
      4. Select Add another column to add more output columns.
      5. Repeat steps 7a-d for as many columns as necessary.
      6. Select Continue.
    8. Verify access to source tables and preview the combined results under the Connect and verify tab.
      1. Select Connect for the data source you want to preview.
        All available connections are provided. If you want to request another connection, select Create new connection. You can see details of the connections by selecting the icon next to the connection.
      2. Select an available connection, and select Connect.
      3. Repeat step 8b for all data sources you want to add to this data interface.
      4. Select Preview on each data source to see the combined data.
      5. Select Preview on the right once all data sources are connected to see the combined data interface.
      6. Select Continue.
    9. Configure access to your data interface on the Set permissions screen.
      1. Add any role you want to grant access to the data interface and determine the access levels.
      2. Select the role by typing the role name.
      3. Select the Read access permission level.

      2. Opcional: Select Edit next to any section to make changes.
      3. Select Finish.
        The final view of the data interface is displayed.
