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.

DBTA: Is it Time for a Professional Code of Ethics for DBAs?
In my many years on the board of directors of the Professional Association for SQL Server (PASS), I frequently exhorted our members to strive for individual achievement and personal excellence. One of the best paths for many SQL Server professionals is through certification, especially if they lack years of demonstrated on-the-job experience. However, certification only paints half the picture. While it might demonstrate, at a minimum, that you passed a test (or several tests) about the database technology, it tells nothing about your standards for good conduct. [READ MORE] … [Read more...]
DBTA: The Trouble with Third-Party Applications
Third-party applications are a very important part of the IT landscape. Many of us have faced the common dilemma of trying to decide whether to build or buy that next important application our organizations need. (By the way, I'm talking about smaller, specialized applications like an inventory management system for the company warehouse, or a practice management system for a doctor's office. I'm not talking about the huge and incredibly sophisticated ERP systems like SAP and Oracle Financials.) [READ MORE] … [Read more...]
DBTA: SQL Server in the Clouds?
The idea of "SQL Server in the cloud" is all the rage as I write this article. Many SQL Server experts already predict the demise of the IT data center and a complete upending of the current state of our industry, in which large enterprises can spend millions of dollars on SQL Server licenses, hardware and staff. I have to admit, when I first heard about this idea, I was ecstatic. What could be better for an enterprise than to have all the goodness of a SQL Server database with none of the hardware or staffing issues? However, on deeper examination, there is much about which to be cautious. … [Read more...]
DBTA:Reaching for Highly Scalable Systems with SQL Server 2008
SQL Server has supported VLDBs (very large databases) for some time now. Back in the SQL Server 2000 days, I recall hearing multi-terabyte databases were unusual but doable. Now, they are commonplace, while databases in the hundreds of terabytes inhabit the part of the map that says "there be dragons." While VLDBs are quite common on SQL Server today, highly scalable systems that can be flexibly extended in the same fashion as Oracle/RAC are less so. So, how do you design a highly available architecture for SQL Server if it's not like Oracle/RAC. [READ MORE] … [Read more...]
