Andy did some research - read the article and see what works and what doesn't! http://www.sqlservercentral.com/articles/Administering/copyingdtspackagestoadifferentserver/638/2006/05/05http://www.sqlservercentral.com/articles/Administering/copyingdtspackagestoadifferentserver/638/This article looks at how partial classes can be used to implement business logic into datasets so that they are more business aware and intelligent. The dataset is an integral part of Microsoft’s new data access model ADO.NET. It introduces a simple offline method for retrieving and updating data. Before using the dataset, you should have an understanding of the Microsoft .NET platform and a basic understanding of the dataset model. http://www.sqlservercentral.com/redirect/articles/1998/2005/08/05http://www.sqlservercentral.com/redirect/articles/1998/One of the best ways to reduce the load on your server and increase application responsiveness is to reduce the number of "round trips" your application makes. This article by Andy Warren shows you a few ways to increase your performance by reducing round trips. http://www.sqlservercentral.com/articles/Performance+Tuning/roundtrips/586/2005/07/15http://www.sqlservercentral.com/articles/Performance+Tuning/roundtrips/586/In the beginning, there was the recordset, a central feature of classic ADO. Like a Swiss army knife, it wasn’t the perfect tool for every job, but given the correct configuration, it could do whatever you needed it to do. The recordset wasn’t always pretty to watch, however, and it came into prominence at a time when client/server applications for which it was optimized were being replaced by web applications. Its dark side included an amazing level of complexity and the number of special cases when it was used with particular providers. http://www.sqlservercentral.com/redirect/articles/1949/2005/07/05http://www.sqlservercentral.com/redirect/articles/1949/The Microsoft® .NET Framework 2.0 delivers an updated ADO.NET that will streamline your data access development efforts. The ADO.NET team has worked with both the System.Xml team and the SQL Server™ team to provide a consistently rich developer experience, crossing technology boundaries from ADO.NET to XML and back. This will all be apparent as you dig into ADO.NET 2.0. There are improvements on so many fronts that you will certainly be pleased. Rather than attempt to list every new and updated feature of ADO.NET 2.0, I will discuss in detail some of the more interesting improvements and focus on performance and flexibility. http://www.sqlservercentral.com/redirect/articles/1810/2005/03/30http://www.sqlservercentral.com/redirect/articles/1810/Learn how to use the new notification technologies in ADO.NET 2.0 and SQL Server 2005 to handle ad-hoc data refreshes. http://www.sqlservercentral.com/redirect/articles/1549/2004/10/18http://www.sqlservercentral.com/redirect/articles/1549/Developing applications for SQL Server usually results in a variety of access methods that the programmers use. A data access layer class, given to the developers, is usually seen as the best practice, but one that isn't usually implemented. In fact, in most software I've built, each developer uses his own method, or may cut and paste from another, but rarely is there a central access class. New Author Patryk Nowakowski brings us his solution using ADO.NET. http://www.sqlservercentral.com/articles/ADO/adonetadataaccesslayer/1444/2004/08/03http://www.sqlservercentral.com/articles/ADO/adonetadataaccesslayer/1444/Need to apply changes to customer (or internal) databases in a calm, controlled manner?

Good code samples help you get started fast! http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/introductiontoadopart2recordsets/529/2003/11/28http://www.sqlservercentral.com/articles/Performance+Tuning+and+Scaling/introductiontoadopart2recordsets/529/Andy returns to the Worst Practice series this week with a short article looking at how connection strings in applications affect what you see in sysprocesses. Perhaps less controversial (in our opinion) that some of the other worst practices, this is something easy to fix and definitely worth fixing!

Along the way, you'll learn how to use the classes, properties, methods, events, and techniques that have made this subject so hard to master. And when you're done, you'll have a reference that you'll use on the job every day.

Using named parameters when you call the proc or passing the values by ordinal? Should you be? Andy thinks 6 out of 10 of our readers will agree with his point of view, we'll be a little more conservative and guess that 5 of out 10 will be closer. http://www.sqlservercentral.com/articles/Miscellaneous/defaultvaluesandnamedparametersforstoredprocs/882/2003/01/08http://www.sqlservercentral.com/articles/Miscellaneous/defaultvaluesandnamedparametersforstoredprocs/882/Perl has been a popular language for Unix administrators for years.
