BUSINESS METADATA: HOW TO WRITE DEFINITIONS

Many errors and accidents are made/caused by misunderstandings of the meanings of terms used.

How many times have you been in a meeting when the words you heard being said did not match what you thought they were?

Many business decisions are made (and later regretted) due to a misunderstanding of the data, and what the data element used in a report is signifying. Some of these accidents and misunderstandings are large enough to be reported in the media. In prior papers I refer to the Mars Lander episode, where the unit of measure was assumed and not made explicit, miscalculations were made and the equipment was lost. Our businesses are filled with many such examples, although not as costly perhaps, are still quite impactful to the business.

SQL Server OLTP vs. data warehouse performance tuning

SQL Server delivers a number of functions for small to large organizations with needs ranging from internally developed applications to third-party off-the-shelf software. With all systems, data collection, entry and analysis at some level is required to meet organizational needs.

As user demands and the volume of data increase, it is imperative that all systems are properly configured and tuned based on the processing needs to meet the organizational requirements. This article will discuss two broad categories of SQL Server processing -- online transaction processing (OLTP) and data warehouses -- and will outline performance-tuning tips for each platform.

SQL Server 2005 - Setup and Deployment

So far, in our series of articles, we have presented the most significant new and enhanced features available in Microsoft's SQL Server 2005 Beta 2, but neglected to provide you with information regarding its installation. While it is more than likely that, by now, you already have accomplished this entirely on your own, we suspect that you still should be able to benefit from a more in-depth analysis of the setup process. Explaining improvements in its design and implementation is the primary purpose of this article.

Steve Jones had a chance to interview Red Gate Software's Simon Galbraith about a variety of topics. An interesting look at the software world through Simon's eyes.
