Article: Using the Ruby DBI Module

I’ve written an article, “Using the Ruby DBI Module,” that discusses
using Ruby DBI to write programs that access databases. The article
is available here:

 http://www.kitebird.com/articles/

I’d be interested in feedback, especially corrections if there
are errors.

The article follows an earlier one, "Using the Ruby MySQL Module,"
that describes the lower-level module on which the Ruby DBI MySQL
driver is based. The earlier article is available at the same site.

Paul: I'll learn much from this article. However -- and this is a nit --
technical writers shouldn't use 'will' for events occurring as the result
of present actions. Also, avoid the use of the passive voice.

Examples:
Here, I will assume that the MySQL module is installed
Here, I assume that the MySQL module is installed
