Using Ruby DBI for database connectivity
http://www.hiveminds.co.uk/node/3098
Ruby DBI is not a true connection layer. Many install it thinking that it will help them connect to their MySQL database and then they find that nothing works. Ruby DBI is an abstration layer or so called "wrapper" class that filters multiple differences in database code into a single interface. So if a Oracle database, MySQL and PostGreSQL all have different syntax for selecting a database row it will not matter in your code. In your code the selection of a row will be the same for all three.
