DBAs Checklist for Designing and Reviewing SQL Server System Architectures
In this tip, Sadequl Hussain will try to list a few areas DBAs need to cover when they are designing new systems or reviewing proposed solutions.
Caching
A SQL Server database can easily be seen as a bottleneck as all data must be retrieved from a single machine. However a caching strategy in your application and alleviate load and improve performance.
SQL Server Indexed Views: The Basics
Views are a valuable tool for the SQL Server Developer, because they hide complexity and allow for a readable style of SQL expression. They aren't there for reasons of performance, and so indexed views are designed to remedy this shortcoming. They're great in certain circumstances but they represent a trade-off, and they come with considerable 'small print'. Jes Borland explains.

Using hash values in SSIS to determine when to insert or update rows

sp_ExecuteSQL can be used to dynamically execute T-SQL code. Learn how to use it and how to add parameters to control what code is executed.
Auditing Matters
We might not be able to stop hacks, attacks, or issues with our databases, but knowing that they've occurred is important. Steve Jones notes that we might need auditing more than security.
Guerrilla Project Management for DBAs
All DBAs need to engage in a little project management to help make sure everything runs smoothly. In this extract from the book Tribal SQL, David Tate explains his system for managing workload, colleagues, and projects, and how not to be just "the guy who says no".
