Managed data access layer for Unmanaged code

Hi,
I have a unique situation here. We have an application which has been
created using Visual C++ 6.0. I am trying to create a new managed (C#) data
access layer for this app so that I can fetch and update various data into
the database. The hurdle is that for ceratin methods there could be a huge
amount of data returned close to 7000 records. I am not very sure whether
this data should be returned as a heirarchy of objects or as XML. I feel
going the object way is much simpler (C#) way but it mught lead to issues in
unmanaged code. WHile with XML, it may be just too much of parsing and schema
validation etc
.
