As multi-tier architectures grow over time, it is often challenging to coordinate those changes across the data, logic and presentation tiers. Unless planned and implemented carefully, an act as simple as adding a column to a table can grind all of the components of your application to a halt. While some of us have comfortable 12-hour maintenance windows every weekend, many of us are bound by service level agreements that are much more strict. So we must find ways to introduce fixes and new features with zero downtime, and without requiring every single component to be refactored at the same time.

That functionality has been expanded in later releases. One aspect of working with XML is creating XML from relational data, which is accomplished utilizing the FOR XML clause in SQL Server.

In this post I want to show a couple of ways to order the data that comes into the pipeline. a number of people have asked me about this primarily because there are a number of ways to do it but also because some components in the pipeline take sorted inputs. One of the methods I show is visually easy to understand and the other is less visual but potentially more performant.

In this tip, I am going to show you how you can create a Data Access Layer (to store, retrieve and manage data in relational database) in ADO .NET. I will show how you can make it data provider independent, so that you don't have to re-write your data access layer if the data storage source changes and also you can reuse it in other applications that you develop.
