Re: DAS C++ Status
Posted by Adriano Crestani <ad...@apache.org>.
The SimpleRead sample was remade and renamed to CompanySamples. Not it
demonstrates not only how to load data from rdb to SDO graph, but how to
modify the graph and apply the changes back to the rdb.
DAS GettingInvolved and sample Readme are updated to these new changes.

Re: DAS C++ Status

-Optimistic Concurrency Control is now implemented on DAS
-testcases are now being tested using postgres rdbms and not firebird
