Hello John,
Thanks for posting here.
From your description, the application you're designing will have three
processing stages:
1. Retrieving data from remote server through webservice, and since you
mentioned that the return object is DataSet, the remote datasource is
relational database, correct?
2. Processing and maniuplating the returned data locally in the application.
3. Update the processed data into Active Directory.
Here are some of my general suggestions for the above three stages:
#1 Generally, for relational database table/records, we would consider
designing some custom classes to represent them in our program so that our
code just simply deal with relational data as normal class objects. This is
commonly called O-R mapping. .NET framework support creating typed Dataset
for conveniently accessing and manipulate relation database data which is
very like a O-R mapping object through it is not a pure one. So you can
consider return typed dataset from the remote datasource for the client
application to maipulate them with strong-typed objects.

And as for the webservice call, since .net has provide proxy generator(the
VS IDE's add webreference or the wsdl.exe tool), it will help automatically
generate strong-typed webservice client proxy, we don't need to worry too
much about this.
#2 As for the local processing and manipulation, would you provide some
further info on this? I think here we should design some classes dedicated
for these data manipulating. And the design also rely on the classes we
used in #1, the processing class/interfaces would vary depend on how you
design the data access objects(use custom classes or typed dataset or
normal dataset ...)
#3 for the AD querying/updating, the .net framework has provided the
System.DirectoryServices namespace for ADSI programming, you can further
implement some custom helper classes which expose some specific interfaces
for your scenario. For example, you can create a certain class which
encapsulate all the AD updating operations as its member functions.
BTW, you can find some good articles and guidelines in the MSDN pattern &
practice center:

All of these are quite general opinions, if you have any detailed cases or
problem, please feel free to post here and we can have some further
discussion on them.
Sincerely,
