+
+### Construction of OData Client
+
+    ODataClient odata = ODataClientFactory.getClient();
+    odata.getConfiguration().setDefaultPubFormat(ContentType.APPLICATION_JSON);
+
+### Construction of a client entity and create request
+
+    ClientObjectFactory factory = getClient().getObjectFactory();
+    final ClientEntity entity = factory.newEntity("OData.Demo.Manufacturer");
+    entity.getProperties().add(factory.newPrimitiveProperty("Name", factory.newPrimitiveValueBuilder().buildString("MyCarManufacturer")));
+         
+    final URI targetURI = getClient().newURIBuilder(serviceUrl).appendEntitySetSegment("Manufacturers").build();
+    final ODataEntityCreateRequest<ClientEntity> createRequest = getClient().getCUDRequestFactory().getEntityCreateRequest(targetURI, entity);
+
+### Add a create request to a changeset
+
+    BatchManager payloadManager = getClient().getBatchRequestFactory().getBatchRequest(serviceUrl).payloadManager();
+    final ODataChangeset changeset = payloadManager.addChangeset();
+     
+    changeset.addRequest(createRequest);
+
+### Construction of a query request
+
+    final URI targetURI = getClient().newURIBuilder(serviceUrl).appendEntitySetSegment("Manufacturers").appendKeySegment(1).build();
+    final URI uri = isRelative ? URI.create(<ServiceUri>).relativize(targetURI) : targetURI;
+     
+    ODataEntityRequest<ClientEntity> queryReq = getClient().getRetrieveRequestFactory().getEntityRequest(uri);
+    queryReq.setAccept(ContentType.APPLICATION_JSON);
+
+### Add query request to payloadManager
+
+    payload.addRequest(queryReq);
+
+### Fetch the batch response
+
+    final ODataBatchResponse response = payload.getResponse();
+     
+    final Iterator<ODataBatchResponseItem> responseBodyIter = response.getBody();
+    final ODataBatchResponseItem changeSetResponse = responseBodyIter.next();
