In data mining, we sometimes need to perform techniques such as Z-score normalization on numeric data type columns to prevent one column from skewing or dominating the models produced by the machine learning algorithms. Dallas Snider explains how to perform this in SQL Server with T-SQL code.
If you can examine and understand execution plans, you can achieve better understanding of the database system and you will write better database code. Grant Fritchey shows you how.
In this chapter we will talk about security recommendations for SQL Server Data Mining.

Grant Fritchey reviews Midnight DBA's Minion Reindex, a highly customizable set of scripts that take on the task of rebuilding and reorganizing your indexes.
How do you find time for learning? More importantly, Steve Jones asks if you find time for actual use of your knowledge.
The easiest way to determine if there is encrypted data in a database is to get that information from whoever wrote the application. Aside from that, there are a few things you can look for which would suggest that you have encrypted data in a given database.
This week Steve Jones talks a bit about problem solving and how you should approach the issue.
