Last month, I began a series of articles describing database application benchmarking. In the first article, I told you about different ways that you can construct your own database application benchmark. However, you don’t have to reinvent the wheel. The Transaction Processing Council (www.tpc.org) has already created a large number of database benchmarks that are extremely useful and informative. I also described last month how the TPC provides several different types of benchmark tests. For example the TPC-C and TPC-E benchmarks are extremely useful for measuring transaction throughput. … [Read more...]

Read the New TPC Database Benchmarking Series
April 22, 2013 by Leave a Comment
Let's talk about database application benchmarking. This is a skill set which, in my opinion, is one of the major differentiators between a journeyman-level DBA and a true master of the trade. In this article published in my monthly column at Database Trends & Applications magazine, I'll give you a brief introduction to TPC benchmarks and, in future articles, I'll be telling you how to extract specific pieces of valuable information from the published benchmark results. But let's get started with an overview … read more. Many thanks, -Kevin … [Read more...]

April 5, 2013 by Leave a Comment
The initial release of Database Lifecycle Management is now available on MSDN. The site is something called "curated content". This means it's a single consolidated location to look up lots of disparate articles and content, all in one easy to search location. This “curated content view” contains the best content, video, and community-centric information from Microsoft, including topics like: SQL Server Data Tools · Get started with sample projects, code samples · Video demos by Gert Drapers (blog) · Script common data portability tasks using Sqlpackage.exe · Link to the … [Read more...]
SQL Dialects
April 1, 2013 by Leave a Comment
Many database vendors provide their own dialect of SQL to supplement the standard. For example, conditional processing, error handling, and flow-of-control statements are often provided by database vendors as an element of their own dialect of the SQL standard. The ANSI SQL standard SQL/PSM (Persistent Stored Module) package describes many features associated with programming stored procedures and incorporates many of the extensions offered by these dialects. However, the implementation of SQL/PSM is not consistent or reliable across all database vendors. Some popular dialects of SQL … [Read more...]
SQL History and Implementation
April 1, 2013 by Leave a Comment
In the early 1970's, the seminal work of IBM research fellow Dr. E. F. Codd led to the development of a relational database product called SEQUEL, or Structured English Query Language. SEQUEL due to some legal hurdles was changed to ultimately SQL, or the Structured Query Language. IBM, along with other database vendors, wanted a standardized method for accessing and manipulating data in a relational database. Although IBM was the first to develop relational database theory, Oracle is widely credited with being first to market and popularize the technology. Over time, SQL proved popular … [Read more...]
Introduction to the Relational Model and ANSI SQL
April 1, 2013 by Leave a Comment
Relational database management systems (RDBMS) such as those covered on this website are the principal engines of structured data systems worldwide. They enable a multitude of users to quickly and simultaneously access, create, edit, and manipulate data without impacting other users. And they enable developers to write useful applications to access their data while providing administrators with the consistent and reliable capabilities they need to maintain, secure, and optimize organizational data resources. An RDBMS may be defined as a system whose users view data as a collection of tables … [Read more...]
