<p>RDB DAS provides a generic data access service that provides
transformation capability between SDO data graphs and relational databases and
vise versa. </p>
<p>The following diagram illustrates these two capabilities in
a typical client interaction.The client
starts by reading a graph of data specified by some query.The client then makes modifications to the
graph, possibly by adding elements, and then requests the DAS to push the
changes back to the database.</p>

<p>The following diagram illustrates the high level object diagram for DAS</p>

<p>To further explore the benefits of DAS please refer to white
paper "DAS White Paper: The Data Access Service" on the <a href="http://incubator.apache.org/tuscany/documentation.html">Documentation

<em>Copyright © 2006, The Apache Software Foundation</em><br/>
Apache Tuscany is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Web Services PMC.
Incubation is required of all newly accepted projects until a further review indicates that the infrastructure,
communications, and decision making process have stabilized in a manner consistent with other successful ASF projects.
While incubation status is not necessarily a reflection of the completeness or stability of the code,
it does indicate that the project has yet to be fully endorsed by the ASF.
