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/Last 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. Gotta read it! http://www.sqlservercentral.com/articles/Performance+Tuning/reducingroundtripspart2/588/2002/02/06http://www.sqlservercentral.com/articles/Performance+Tuning/reducingroundtripspart2/588/In three previous articles Andy has done a very basic introduction to the ADO connection, command, and recordset objects. In this wrap up article he talks about how to use the power of ADO client side filtering and disconnected recordsets, then adds some code which shows how to combine all the objects. ADO is not simple, but Andy has done a good job in limiting his dicussion to the things you REALLY need to know about ADO to get started. http://www.sqlservercentral.com/articles/Performance+Tuning/introductiontoadopart4combiningitall/537/2001/12/07http://www.sqlservercentral.com/articles/Performance+Tuning/introductiontoadopart4combiningitall/537/
