Chris works through the list of options. If you're building web/disconnected apps and need anything besides last update wins, this one is for you. http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/dealingwithchangingdata/1233/2003/12/19http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/dealingwithchangingdata/1233/Using Interface-Based Programming Techniques in SQL ServerProgrammers can most commonly relate to interface-based programming in their programming language. This is harder to accomplish in SQL Server though. In this article by Chris Cubley, he shows you how to build interfaced-based SQL. http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/sql_interface_final/732/2002/07/19http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/sql_interface_final/732/Performance Comparison: Data Access TechniquesArchitectural choices for data access affect performance, scalability, maintainability, and usability. This article focuses on the performance aspects of these choices by comparing relative performance of various data access techniques, including Microsoft® ADO.NET Command, DataReader, DataSet, and XML Reader in common application scenarios with a Microsoft SQL Server™ 2000 database.http://www.sqlservercentral.com/redirect/articles/620/2002/03/01http://www.sqlservercentral.com/redirect/articles/620/Reducing Round Trips - Part 2Last week Andy started a discussion of the various ways you can reduce the number of round trips to the server. This week he continues by looking at a method he used recently to do client side caching of data to eliminate the round trip altogether.
