+ * implement queries from both in-memory and database-backed collections.
+ *
+ * For database backed collections this allows very efficient access by
+ * utilizing the query APIs, for example SQL in the ORM. Applications using
+ * this API can implement efficient database access without having to ask the
+ * EntityManager or Repositories.
