Administration Guide
Before a BEA Liquid Data for WebLogic query can access data in a data view, the data view must be configured as a Liquid Data data source. Data views are derived from stored queries. Only one data view can be created from a stored query. You can also deploy data views directly from the Data View Builder. For instructions on how to create data views, see Building Queries and Data Views and To Create a Data View from a Stored Query.
Once configured, data views with data source descriptions will show up as data sources available for use in any EJB client, such as the Data View Builder, that connects to this server. For more information, see Using Data Views as Data Sources in Building Queries and Data Views.
The following sections are included:
The Data View tab of the Liquid Data Administration Console displays a list of data views configured in Liquid Data. You configure the data views from the Stored Queries tab of the Liquid Data Administration Console.
Figure 12-1 Data Views Tab of the Liquid Data Administration Console
From the Data View tab, you can perform the following:
Note: You can also view all data sources from the All Data Sources configuration tab on the Liquid Data node in the Administration Console, as described in Viewing and Accessing All Configured Data Sources.
To access a data view as a data source from Liquid Data, you must first create a data source description. The data source description provides Liquid Data with the necessary information to access the query defined in the data view and use it as a data source for other queries.
Note: You can create and deploy a Data View directly from the Data View Builder instead of going to the Administration Console. For details, see Building Queries and Data Views.
You create new data view data sources from the stored query tab of the Liquid Data Administration Console. To create a data view data source description, see To Create a Data View from a Stored Query.
You can delete a data source description that you no longer need. Deleting a data source description does not remove the stored query to which it refers; it removes only the data view description from the repository.
Note: You must have access to the console and modify
security permissions on the data view to delete the data view data source description. For more information, see Defining Liquid Data Roles and Groups.
To remove a data source description for a data view:
A table of configured Liquid Data data views is shown (see Figure 12-1).
You can define a security policy for each data source from the Data Views tab of the Liquid Data Administration Console.
Perform the following steps to define a security policy on a Liquid Data data view data source.
