Description of this site
Here you can find some formulated thoughts of my experience about Oracle and other RDBMSes. MySQL stuff is old and most probably out of date.
If you don't know what is Oracle then you can visit wikipedia for more descriptional and historical info.
The site is running since May 2006, here you can find longer works. Smaller thoughts and some other stuff is also in my blog. According to google analytics there are 156 countries out of ~193 whose people have at lest once visited this site.
Lately two most popular articles were SQL Join types and Overview of long running operations in Oracle. Since October 2007 I'm also writing (at least now the only) blog about relational database management systems in Latvian.
