+<p>This Tutorial shows how to use the Apache Olingo Library for CRUD 
operations on an existing OData Service.
+Therefore it contains the Explaining the Client section which explains how to 
implement the CRUD operations based on sample code.
+For creating a simple odata service refer the section Basic Tutorial: Create 
an OData V4 Service with Olingo in Olingo V4 tutorial</p>

+<p>With this Quickstart guide the runnable sample client and an sample service 
is created within a few minutes. Therefore it just requires an installed Java 6 
Runtime, Maven 3 and an internet connection</p>
+<ol>
+<li>Create a sample maven project and name it OlingoSampleApp.</li>
+<li>Create a new package org.apache.olingo.samples.client under this
+    project.</li>
+<li>Create a class OlingoSampleApp.java under package
+    org.apache.olingo.samples.client.</li>
+<li>Copy the entire <a href="OlingoSampleApp.java">sample client code</a> into 
this class.</li>
+<li>Copy the <a href="OlingoSampleApp.java">sample pom file</a> into this 
projects pom.xml file.</li>
+<li>Run OlingoSampleApp against sample Service</li>
+<li>In order to fetch all the dependencies in the pom.xml file run
+    eclipse:eclipse command on the sample client project</li>

+<p>For an OData Service the Entity Data Model (EDM) defines all metadata 
information about the provided data of the service. This includes all entities 
with their type, properties and relations, which entities are provided as 
entity sets and additional functions and operations provided by the OData 
Service. The EDM also have to be provided by the OData Service via a unique URI 
(e.g. http://localhost:8080/DemoService/DemoService.svc/$metadata) in the EDMX 
format.
+This fact is important because the Apache Olingo library requires the metadata 
for serialization and de-serialization of the data of an entity (e.g. the 
validation of the data is done against the EDM provided metadata). Hence the 
first step in this sample is to read the whole EDM of an OData Service.</p>

href="#create-entity" title="Permanent link">&para;</a></h3>
+<p>To create an entity a HTTP POST on the corresponding entity set URI with 
the whole entity data as POST Body in a supported format (e.g. atom-xml, json) 
has to be done. With Apache Olingo the required POST Body can be created 
(serialized) with the methods available on ClientObjectFactory. This method 
creates a ClientEntity which contains the content (i.e. the required POST Body) 
which then can be send to the server. If the entry was created successfully an 
HTTP Status: 201 created will be returned as well as the complete entry.
+For simplicity in the code sample below the prepare and execute of the POST 
and the read of the response is separated (see Part 1: Post and Part 2: 
Read).</p>

response will be the ClientEntity with no content.
+If the entry was updated successfully an HTTP Status: 204 No content will be 
returned.</p>

+<p>For deletion of an entry just a DELETE request is necessary on the URI of 
the entity. Hence the Apache Olingo is not necessary to serialize or 
de-serialize anything for this use case.</p>

+<p>So the code for delete of an entry the  DELETE request URI is an Entity for 
which a key value is required for creation of the absolut uri. Via execute() 
method the request is done against the uri and the responding http status code 
is returned, which is, if the entry was deleted successfully, an HTTP Status: 
204 No content.</p>
