Like Rogue Wave®  Views data sources, a Server data source can be local or global. A global Server data source means that all its Views data sources are global and, therefore, accessible throughout the application.

Typically, one of the possible situations is the following: suppose you want to use a large server relation in several panels of your application

Because it may be costly to retrieve the contents of such a relation, you may want to use a global Server data source, whose Views data sources will be accessible from any panel.

By default, Rogue Wave Server creates local Server data sources and local Views data sources that will be accessible only from the panel where they are stored.
