Override the generated ORM update/delete/insert logic with your own through stored procedures. The video also shows in detail how to use the SQL Profiler to monitor the changes in the ORM from generated SQL to our custom SQL stored procs. Since we're just writing SQL, the same techniques apply to both C# and VB developers.

In this webcast I dive pretty deep into Data Access and talk about some architectural decisions I need to make, specifically how to get Linq To Sql to map to my model properly. I also go over some feedback I received at the MVP summit last week.

Nine Inch Nail Time
Steven Harman suggested I run a Spike (a quick prototyping exercise to test out a theory) to make sure that my data access strategy will work with an actual database. Good idea.

I quickly ran into some issues with Linq To Sql, but found some neat ways to keep things clean and tidy so I don't explode my database all over my happy little application.

Modern applications operate on data in several different forms: Relational tables, XML documents, and in-memory objects. Each of these domains have profound differences in semantics, data types, and capabilities, and much of the complexity in today's applications is the result of these mismatches. Anders Hejlsberg, Microsoft Technical Fellow and Chief Architect for Microsoft Visual C# and LINQ, will explain how LINQ (Language Integrated Query) unifies these programming models and dramatically improves the experience of creating data intensive Web applications. Anders promises to have few slides and lots of live code demos!
