The Potential of Joins
An article about how we underestimate the power of joins and degrade our query performance by not using proper joins
Another Look at Tuning Big Data Queries
Most large organizations have implemented one or more big data applications. As more data accumulates internal users and analysts execute more reports and forecasts, which leads to additional queries and analysis, and more reporting. The cycle continues: data growth leads to better analysis, which generates more reporting. Eventually the big data application swells with so much data and querying that performance suffers.
How do you develop and deploy your database?

Small Leadership
Today Steve Jones talks leadership, and the value it can bring to your team if you display just a little of it.
The DRI Subject of References
A database must be able to maintain and enforce the business rules and relationships in data in order to maintain the data model. It does this through referential constraints. They aren't complex, but are powerful, especially with the means to attach DRI actions to them. Joe Celko explains all, and pines for the ANSI CREATE ASSERTION statement.

Error handling with try-catch-finally in PowerShell for SQL Server
PowerShell V2 introduces the "try-catch-finally" statements, similar to those you already use when you write .NET code. "Try-catch-finally" encloses a block of script that is likely to produce errors under specific circumstances and therefore helps you to keep your code organized. This article is a short usage guide for this error handling construct.
Collect Data from Multiple Instances Using SSIS and Powershell
Use SSIS to pull data from multiple instances. Combine with powershell to run multiple instances simultaneously.
The Query Store
This week Steve Jones talks about the query store after an article was released describing it.
The Importance of Caching
Performance tuning and optimization definitely have their place in minimizing SQL Server Licensing costs – by helping keep CPU utilization low. But it’s important to remember that the fastest and most efficient query possible is the one that you never execute against your SQL Server. That might sound trite, but it’s at the heart of caching – which is key to helping organizations save significant money on SQL Server licensing costs while simultaneously enabling better application performance and increased scalability.
