Seldom has a SQL Server Service pack had such an effect on database development as when SQL Server 2012 SP1 introduced selective XML indexes. These transform the practicality of querying large amounts of XML data. Seth Delconte demonstrates how and why this feature makes all the difference.

Have you ever had to write a bunch of TSQL to do some data analysis on the table data in your database. If you have you'll know that this can become a fairly time consuming and tedious task? SQL Server 2012 Integration Services has a feature called the Data Profiling task that can help you perform this analysis much easier and faster (this feature is also available in SQL Server 2008). This task can help you find potential issues with your existing data as well as help you become more familiar with the data in a database that you have just started managing.

As a production Database Administrator, I do not want to give Developers direct access to the SQL Server Agent job log especially for servers in the DMZ. Another problem we have is that when there is a lot of log data for a job, the default job log doesn't contain the full log detail and that makes it harder to troubleshoot. Most of all, we are trying not to use a different code set for deployment based on the environment. Basically we want to use the same methods to deploy our jobs to Development, Test and Production.

The most critical task for all DBAs is to have a Backup and Recovery strategy that ensures, every day, that in the event of a disaster they can restore and recover any database, within acceptable limits for data loss and downtime. Even with all the required backups in place, it's easy to miss subtle failings in the overall plan that can, and eventually will, defeat your recovery plans.

In February 2008, Microsoft announced a record-breaking data load using Microsoft® SQL Server® Integration Services (SSIS): 1 TB of data in less than 30 minutes. That data load, using SQL Server Integration Services, was 30% faster than the previous best time using a commercial ETL tool. This paper outlines what it took: the software, hardware, and configuration used. We will describe what we did to achieve that result, and offer suggestions for how to relate these techniques to typical scenarios. Even for customers who don't have needs quite like this benchmark, such efforts can teach a lot about getting optimal performance.

There are several different ways of restricting access to SSIS packages and confidential information they contain. However, preventing unauthorized users from running or viewing the content of your code is not the only security measure that you should take into consideration.
