antony commented on TUSCANY-3671:
---------------------------------

DAS is the only medium for SDO to talk to RDBMS? is there any other medium?

I had successfully executed this company-webapp sample. But i couldnt process further, as i didn't find how to get the SDO DataGraph from this DAS reference...

Command read = das.getCommand("all companies");
        DataObject root = read.executeQuery();
        return root.getList("COMPANY");
...
...
....  
das.applyChanges(root);
..
..

> I could not find any samples or piece of code on how SDO interact with RDBMS. It will be good if we have one in the sample provided. Can someone plz tell me on how to get the HelperContext for the RDBMS. All samples explain only about connect to XML/XSD not to RDBMS. I tried with DAS but i am not sure how to map DAS with SDO.  Can someone plz explain the steps on how to connect SDO with RDBMS.
