In the last several articles on Database Trends & Applications, I've been describing the benefits of reading and analyzing the benchmarking case studies released by the Transaction Processing Council. I've given you from a broad overview of the TPC benchmarks and shown ways that the vendor-published TPC benchmarks can help you save money and how the vendor-published TPC benchmarks must explain in disclaimers how they tweak their workloads. I have described how to run your own benchmarks and explained how to properly prepare your environment for a benchmark test.

Back when my day-to-day duties included database administration work and enterprise architecture, I became rather obsessed with the idea of operational excellence.  I read everything I could on the topic.  I made a list of favorites, which became somewhat shabby over time, as I dog-eared important pages and scribbled notes in the margins.  (Perhaps that list of favorites might, in and of itself, make a good blog post).  Fast-forward a decade and I'm still mightily interested in operational excellence for IT organizations.  It's just that so much good material is available for free on the … [Read more...]

DBTA: What’s the Fuss about Data Deduplication?

Listen to a group of database professionals talk for awhile and someone will eventually bring up the topic of data deduplication. Data deduplication is a means  to eliminate redundant data, either through hardware or software technologies.  To illustrate, imagine you've drafted a new project plan and sent it to five teammates asking for input.  That single file has now been reproduced, in identical bits and bytes, on a total of six computers. If everyone's email inbox is backed up every night, that's another six copies backed up on the email backup server.  Through data deduplication … [Read more...]

DBTA: The Big Keep Getting Bigger

In this season of recession and financial meltdowns, a common question seems to be, "How big is ‘too big to fail'?" Titans of the financial industry made big bets with lots of risk and, when they didn't pan out, American society overall has to pay the price.  But, that aside, the very scale of our financial system, by just about every metric, has reached amazing heights, be that number of financial transactions per second, number of traders, number of funds traded, amount of money changing hands—you name it.

Video: SQL Server Disk Optimization

Since the release of SQL Server 2005, companies have been investing heavily in SQL Server for their business-critical applications. DBAs are now challenged with supporting ever-growing datasets and making efficient use of allocated disk space in both production and enterprise storage environments. Yet DBAs seldom have a clear picture of their data storage and therefore cannot determine whether they are getting a worthwhile return on their storage investment or if an out-of-disk situation is looming. In this presentation, Kevin will address these challenges and explore methodologies to help … [Read more...]

Sequels for SQL: Dec 17, 2009

In the Sequels for SQL series, I point you to sites where you can go beyond the nose-to-the-grindstone resources that we see every day as SQL Server professionals.  (My favorite resource for pan-SQL Server pointers is Steve Jone's Database Weekly email newsletter.)  These are the story that comes after and outside (the sequels) of our daily working lives (the other SQL).  Let's broaden our horizons together.  If you hit on an interesting but overlooked topic, I'd like to hear from you. SQL Server: We live it.  We love it. When Jimmy May talks, I listen.  Not just because he's a personal … [Read more...]
