&lt;number&gt; Apache Tuscany has a RDB DAS Apache Directory is working on a LDAP DAS There are couple teams at IBM working on other DAS Implementations (e.g IMS team) SCA Partners have their own implementations as well
&lt;number&gt; See more later – best practice pattern
&lt;number&gt; Open the box and see what we have
Pick out gen classes and the fact that the impl implements DataObject
&lt;number&gt; Containment Non containment Note use of ID to define unique reference
As distinct from generated classes shown before
Typed must be available for e.g. deserialization
DataObject instance doesn’t have a name or URI!
Just in time SDO info, to help with understanding of WSDL message body contents
This is an isMany = false example – integrity preserved for isMany = true also, e.g. if one of many children displaced by a List operation
Example of creating xml representation including change data
&lt;number&gt; Basically, 2 capabilities are read and write … but in terms of SDOs
All this adds to our knowledge to date is that the DAS can be accessed via clients directly, or in an SCA environment by the DAS component.
Take entity bean and create an SDO session bean facade
