A data source group contains references to multiple OData-enabled data source definitions, enabling you to access them all with the same resource path.

Note:

The following limitations apply in data source sharing scenarios.

  • If you plan to share a data source group with another user or a tenant, the member data sources of the group must also be shared.
  • Data source groups may only be created with member data sources that are owned by the creator. In other words, the creator of a data source group cannot include a data source shared by another user in the data source group he or she is creating.

Take the following steps to create a data source group.

  1. Navigate to the Data Sources view by clicking the data sources icon .
  2. Click the Data Source Groups tab. The Data Source Groups page opens.
  3. Click +NEW GROUP. The Create a Data Source Group page opens.
  4. Enter a unique name to identify the data source group in the Data Source Group Name field.
  5. Optionally, enter a description for the data source group in the Description field.
  6. Optionally, specify a value in the Maximum Length of Entity Name field to control the length of the entity prefix. You can specify values from 10 to 128. Names that are longer than the specified value are altered to fit.
  7. Record the OData Access URI. The value of this URI cannot be modified. This is the URI you will use to expose your data and configure your application.
    Note: You may also obtain the OData Access URI after saving the data source group by clicking the OData URI icon.
  8. The OData Data Sources section displays the list of data sources that have been enabled for OData. These data sources have a defined schema map and an associated model.
    1. Select the data sources that you want to add to the group.
    2. For every selected data source, enter a unique prefix. The prefix can be a combination of alphanumeric characters but must not start with a number. The length of the prefix must be less than half the value of Maximum Entity Name Length. For example, if the value of Maximum Length of Entity Name is 10, the prefix must be no more than 5 characters long.
  9. Click Save & Close. The new data source group is displayed on the Data Source Groups page.
