Welcome to my BeyeNETWORK Blog. This is going to be the place for us to exchange thoughts, ideas and opinions on all aspects of the information quality and data integration world. I intend this to be a forum for discussing changes in the industry, as well as how external forces influence the way we treat our information asset. The value of the blog will be greatly enhanced by your participation! I intend to introduce controversial topics here, and I fully expect that reader input will "spice it up." Here we will share ideas, vendor and client updates, problems, questions and, most importantly, your reactions. So keep coming back each week to see what is new on our Blog!

Recently in Analytic Databases Category

Before my current career in data management, I had a previous life as a software developer, working on designing and implementing compilers for Fortran and C for massively parallel processing (MPP) computers, and while I have been working on data quality and BI for the past 13 years or so, I still have a great interest in the high performance computing space. Recently I have had the opportunity to indulge that interest with respect to learning about the distributed/parallel programming model that Google has championed called MapReduce, and its relationship to the use of analytical database management systems.

There are some similarities, some differences, and ultimately, the two paradigms are complementary when it comes to supporting end-user business needs. If you are interested in the thought processes, check out this analysis paper, funded by Vertica, which compares and contrasts both high performance approaches.

Sybase has just posted a white paper that I wrote on high performance analytics using column-oriented databases. Despite my recent (10+ year) foray in the data world, my original background is in high performance data parallel computing. Parallel columnar database systems reflect the best of both worlds I have lived in, and I hope you guys find the paper interesting!
