A data source is a source of information that can be queried. Liquid Data supports querying the following types of data sources: relational databases (RDBMSs) via JDBC, XML files, Web Services, application views, and data views (which are the dynamic results of queries stored along with the queries that produce them).
This chapter describes how to view and access configure BEA Liquid Data for WebLogic data sources using the All Data Sources configuration tab on the Liquid Data node in the Administration Console. It includes the following sections:
To view all currently configured data sources:
The tab shows a list of all data sources currently configured on the Liquid Data server to which you are connected.
Figure 6-1 Viewing All Configured Data Sources
The Administration Console displays the configuration tab for that data source.
For more information about editing data source descriptions, see the chapter associated with that data source type. For example, to configure access for relational databases, see Creating a Relational Database Data Source Description.
You can configure security for each data source description by assigning security policies. For more information about Liquid Data security, see Security in Liquid Data.
Permissions determine the tasks that users can perform on data sources in the Data View Builder, Liquid Data applications, and the Administration Console. Users must be logged into the applicable tool with the following permissions:
Perform the following steps to assign security policies to a data source:
You can remove a data source description that you no longer need. Removing a data source description does not remove the actual data source to which it refers. You can remove the data source description using the All Data Sources tab on the Liquid Data node or using the summary tab associated with the data source type.
Note: You must log in with modify
access privledges before you can remove a data source description. For more information, see Defining Liquid Data Roles and Groups.
To remove a data source description:
Note: Removing the data source description does not remove the underlying data source to which the Liquid Data data source description pointed. The process of removing the actual data source varies depending on how the data source is set up. For example, you can use the Repository Tab on the Liquid Data node in the Administration Console to remove source XML files from the repository, as described in Deleting Folders and Files in the Server Repository.
Each Liquid Data server instance must have its own set of data source descriptions. Rather than entering data source descriptions manually on each Liquid Data server, you can simply copy the data source description from one server to another. The Liquid Data node provides an Import / Export tab that you can use to export the data source description to a file that you can then import on other Liquid Data servers. For more information, see Importing and Exporting Liquid Data Configurations.
