By John Handra on Feb 09

One of the main benefits of an AlwaysOn Availability Group is being able to read off of the secondary replicas.

Describing why the products became popular provides us with the opportunity to perform a high-level analysis of the relational and NoSQL models and architectures.

T-SQL Query- Search for Column Details by Name

By Brian Wineland on Jan 12

Oftentimes, I am presented with queries from a client with a myriad of joins that have no table aliases. In order to improve performance, I often will have to create temporary tables from pieces of the query, and sometimes they need to be created manually as opposed to performing a SELECT INTO.  Having to search through all of the tables through the GUI manually to determine the proper information on the columns can be quite a pain and a waste of time.  In an effort to better utilize my time, I created a simple query that will return where the column resides as well as everything you need to know about the column and more.

SQL Server Reporting Services- Adding SSRS to SQL Server Clustered Instance

By Corey Beck on Dec 29

I recently was tasked with a project to consolidate several SQL 2005 database servers down to one existing SQL 2012 database cluster.  While working on this project, I found that one of the database servers needing to be consolidated was utilizing SQL Server Reporting Services (SSRS), but the existing cluster was not configured for Reporting Services.  SSRS is not cluster aware, so adding this feature to an existing clustered instance is not straightforward and will likely lead to a rule check failure on the “Existing clustered or cluster-prepared instance” rule.  Well today is your lucky day, as I’m going to show you exactly how to get beyond this error and on your way to making your SSRS cluster aware!

Data Administration- Laying the Foundation for High Quality Database-Driven Applications

By Chris Foot on Dec 14

I use the title "Data Administrator" loosely to describe the functions these IT specialists provide. I use it for clarity only in this article because I think it oversimplifies the important role they play. Data Administrators are more aptly titled "Protectors of the Organization's Critical Data Assets." From establishing proper naming conventions to implementing corporate-wide data management policies, the services they provide range the spectrum.

In the world of big data, we are always trying to lighten our storage footprint.  Luckily for us, Microsoft has introduced data compression as an enterprise-level feature to aid in conserving storage.  Not only are you able to save on storage, you will also dramatically reduce the number of I/O requests.  Knowing that the disk subsystem is the slowest part of our environments, these fewer I/O requests needed for retrieving data will lead to an increase in performance.
