SQL comparison updates: Informix, JDBC

A reader of my SQL implementation comparison page suggested that I keep a change log for the page. Currently, I don't want to keep a detailed log, but I'll add blog posts here when I've made changes which are somewhat significant, tagging the posts 'sqlpage'.

Today, I added a new section related to JDBC, because I'm tired of having to spend time looking up details like JDBC driver names and connection URLs in manuals. (I don't work much with Java, so I keep forgetting where to find this stuff when I need it.) The section is far from complete.

I also started coverage of the Informix database, as I've recently become responsible for an important Informix database at work. Informix was once a very important player in the database game, but the story goes that the Informix company suddenly started getting managed very badly -- and at some point IBM bought Informix. Since then, IBM's strategy for Informix has been rather unclear. I have a personal, very weakly founded theory: I think IBM is positioning Informix as the place where the exciting new developments happen first; and when the new features are known to work well, they are introduced to DB2. This may not be a bad role for Informix.
