As a developer of the OData service, you have to know how and where the data
is stored. In many cases, this would be a database. At this point, you would
connect to your database and fetch the requested data with an appropriate SQL
statement. The data that is fetched from the data storage has to be put into an
<em>EntitySet</em> object.
Note that this object has to be of type <em>EntitySet</em>, not
<em>EdmEntitySet</em><br />
The package <em>org.apache.olingo.commons.api.data</em> provides interfaces
that describe the actual data, not the metadata.</p>

<em>Olingo</em> expects from us to provide the data as low-level
<em>InputStream</em> object. However, <em>Olingo</em> supports us in doing so,
by providing us with a proper "serializer".
