Large Data Operations in SQL Server
The articles in the Quantitative Performance Analysis series examined the internal cost formulas used by the SQL Server query optimizer in determining the execution plan and the actual query costs for in-memory configurations. The previous articles restricted the actual query cost analysis to in-memory cases where all necessary data fit in memory so that performance was not limited by the disk configuration. This article provides a first look at queries involving data large compared to available memory and queries involving write operations where performance is limited by the disk configuration.

A case is presented in this article showing that the SQL Server internal cost formulas for I/O operations are based on disk access times. The I/O cost values were fixed several years ago. They do not accurately reflect current generation disk drive performance, nor do they reflect the actual cost of in-memory operations. In addition, the SQL Server execution cost model does not properly account for I/O costs on Insert, Update, and Delete (IUD) operations. For small row count operations, the discrepancy between the internal SQL Server cost model and the actual query costs do not significantly affect the efficiency of the execution plan. On large row count operations, the default plan can be substantially slower than an execution plan that accurately accounts for the number I/O operations involved.

Building Wiki Web Sites with ASP.NET and SQL Server
This article describes some of the advantages that Wiki Web sites provide and how you can use ASP.NET and SQL Server to create your own Wiki. You'll learn how to write powerful parsers using the .NET regular expressions class and you'll discover how to add sophisticated search functionality to your Web sites by using SQL Server's Full-Text Search service.

Imagine you visit a Web site that offers information about .NET. You start reading one of the pages about the String class and then realize that the syntax of one of the methods is incorrect. You click the Edit button, update the syntax of the method, update the example that describes how to use the method, and save your changes so that future readers benefit from your contribution. You've just used a Wiki Web site.

MySQL Makes Waves
You may not have heard of MySQL, but I can almost guarantee you've used its database at some point. If you've ever filled out a form on the Web or purchased something online, there's a good chance the data you provided is stored in a MySQL open-source database. This simple-to-use database is behind many of the transactions that take place on the Internet, because unlike Microsoft's (Nasdaq: MSFT) database products, it's free and it runs on both Linux and Microsoft operating systems.

I've used MySQL many times, and the database does live up to its reputation for being easy to use. I've also worked with many corporate databases and can tell you that MySQL is more than adequate for handling the majority of applications databases are used for.
