Hi,

 In JDBC, to connect into a database you just need to have a driver for 
the database you want to connect to. Once connected you can get the 
metadata of the database and query its properties. Same code and logic 
will work in any database. These are the kinds of freatures I'm looking 
if there is an equivalent in Ruby.

Thanks
Jag
