+ * <li>{@link Read} for computing a single result synchronously
+ * <li>{@link AsyncRead} for computing a single result asynchronously
+ * <li>{@link MultiRead} for computing a collection of results synchronously
+ * <li>{@link AsyncMultiRead} for computing a collection of results
+ * asynchronously
+ * <li>{@link Write} for reading and writing synchronously
+ * <li>{@link WriteOnly} for writing synchronously
+ * </ul>
+ * <p>
+ * The standard AsyncRequestProcessors are
+ * <ul>
+ * <li>{@link AsyncReadGraph} for performing requests during other requests
+ * <li>{@link Session} for initiating a transactions for performing requests
+ * <li>{@link MergingGraphRequestProcessor} for merging several requests in a
+ * single transaction
+ * </ul>
+ * 
+ * Database services (see e.g. {@link Session}) are available from implemented
+ * {@link ServiceLocator}. For a synchronous counterpart with the same
+ * functionality as AsyncRequestProcessor see {@link RequestProcessor}
