I dont think it is an openness issue.  DRDA, I am guessing, is part of
a server centric architecture.  Since the release of  ADO.NET ( 5
years ago ) and probably SQL Server 2000  Microsoft has gone with the
detachable dataset approach to database serving.  They say such a
database setup is more scalable and is more compatible with server
farms.

 For example, the server side SQL Cursor is still supported by MS, but
its use is discouraged and is not a part of the .NET framework.  You
have to roll your own.  The theory being that the server farm can
serve out a subset of the database as a dataset to the client very
efficiently.  The client then orders and joins the datasets as it
wishes, using the client's resources.  The server side cursor, with
all its built in functionality, puts a heavy load on the server.  So
it does not scale well.
