Abstract
At this point, most of you will know enough about queries from what you have learned so far that you will likely not need any of the material from this chapter. In fact, roughly half of this chapter deals with using queries that will couple your application to a target database, so they should be used with some degree of planning and caution in any case.

Notes
- 1.
In a @NamedEntityGraph annotation it will contain the subgraph nodes for the entire entity graph.
- 2.
A subgraph can be defined for the root type, but in that case it is an additional fetch plan used when the root entity type is being accessed through a relationship.
- 3.
You can share subgraphs within the same entity graph, though.
