Welcome to my attempt to enter the 21st century (hey, it's only beginning its second decade) and use this medium to share some of the ideas, knowledge, and experience some people think I have. I suspect I'll be writing mostly for myself initially, but that's a good thing as long as I'm actually writing: my tendency has been to keep it all in my head. Not only is it of limited use there, I feel that my head is actually not a very good place these days for thoughts to thrive.
The main theme of this blog is spatial data management, meaning what a spatially enabled database management system can do with spatial information. Subthemes are geospatial data, where that spatial information is tied to a specific location on the Earth (this applies to pretty much everything discussed in this blog); spatiotemporal data management, in which the time dimension is considered of equal importance; and round-earth spatial data management, for which the term geodetic, originally from a product name, has stuck as a short-hand moniker. I may occasionally delve into application areas such as Geographic Information Systems and Location-Based Services, but that will not be my focus--nor do I think I have that much to offer at that level.
The database management systems I know most about are Informix and, to a lesser extent, DB2. This blog will definitely focus on Informix, but DB2, as well as competing products, are fair game. As a side theme, I may digress into database extensibility in general, not just spatial extensions; the Informix term for an extension is DataBlade. Other non-spatial aspects of these systems I will happily leave to other and better minds; this is not a general database blog.
I'll have to develop my own style and publishing practices as I go along. One thing I will attempt to do is to keep blog postings relatively short and digestible. Especially when it comes to detailed prescriptions on how to accomplish some process or formulate some query, I prefer to publish separate articles on developerWorks and link to them from here, usually with some comments and discussion.
As to why I think I am qualified to write this blog: I have been involved in the development and support of spatial software for over twenty years. After a short stint as a geophysicist (what my master's degree says), I became a developer and development manager of image processing and GIS software for a few Silicon Valley start-ups that did not go anywhere. In 1995 I joined Illustra to manage the development of a round-earth spatial database extension; I've been involved with that kind of product ever since, through acquisitions by, first, Informix and, later, IBM, and through a move, ten years ago, out of development and into the field. I now help sell this stuff by doing direct technical sales as well as training my colleagues in the trenches, while keeping close ties with the lab; in IBM terms, I'm the "SME" (Subject Matter Expert) on this topic. I occasionally write articles and present at conferences.
Thanks for reading,
