The alternative to surrogate keys is natural data keys. In order to understand the many substantial benefits of surrogate keys it's necessary to discuss some background on the issues involved.
In this lesson, we revisit usage-based optimization, a subject that we undertook in my article MSAS Administration and Optimization: Simple Cube Usage Analysis, in September of 2003, and MSAS Administration and Optimization: Toward More Sophisticated Analysis in October of 2003. In the earlier articles, we discovered that, among several tools that Microsoft SQL Server 2000 Analysis Services offered us to assist in the maintenance and optimization of our cubes, two of these tools, the Usage Analysis Wizard and the Usage-Based Optimization Wizard, leveraged the usage-based optimization features of Analysis Services.
Data modeling is no doubt one of the most important and challenging aspects of developing, maintaining, augmenting and integrating typical enterprise systems. More than 90% of functionality of enterprise systems is centered round creating, manipulating and querying data. It therefore stands to reason that individuals managing enterprise projects should leverage on data modeling to execute their projects successfully and deliver not only capable and cost effective but also maintainable and extendable systems
Definitely written for backup ISVs, but this is an interesting architectural article as to how the backup systems will work in SQL Server 2005.
Writing outer joins can be more difficult than it appears at first glance. Steve Jones examines this less often used query technique and brings to light a few places where you can lose data.
IT leaders from enterprises around the world have realized that acquiring and implementing commercial off-the-shelf (COTS) application packages is a smarter thing to do, than the traditional approach of developing home-grown applications. This may not be the fit-for-all solution, but it makes sense from a cost, time to market and resource standpoint. Selection and acquisition of the software package is just the first step. How the software package brings value through successful implementation, is critical to the business. Internal groups as well as industry analysts will closely watch COTS package implementation in the organization.
This article covers a few, more advanced topics about the usage of clustered indexes in SQL Server. Not only will I try to convince you of the absolute necessity of using clustered indexes, I'll also give you some tips on how to use them in a not so obvious context.

Access can be a very quick and easy to use tool for working with SQL Server data and for quick and dirty projects, it might be the best tool. But there can be performance issues at times and Andy Warren digs into some of these based on some analysis of what Access does behind the scenes.
In this sample chapter, you'll get a full tutorial on how to create an end-to-end SSIS package including transformation, looping and archiving of files.
