Is that good > idea to store a database handle in a base class? No, don't do that. You should pick one approach for managing database handles, whether it's Apache::DBI or something else, and only use that. If you keep a database handle around in a global somewhere, it may time out and nothing will ping it because you're not calling connect() on each request. - Perrin
