.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is the \f(CW\*(C`DBI\*(C'\fR model class. It has been rewritten to use DBIx::Connector since it's internal code
that deals with connection maintenance has already been ported into there. You now have two options for 
doing custom models with Catalyst. Either by using this model and any related modules as needed
or by having your custom model decoupled from Catalyst and glued on using Catalyst::Model::Adaptor
.PP
Some general rules are as follows. If you do not wish to use DBIx::Connector directly or \s-1DBI\s0 and setup 
connections in your custom models or have glue models, then use this model. If you however need models that 
can be re-used outside of your application or simply wish to maintain connection code yourself outside of
the Catalyst, then use Catalyst::Model::Adaptor which allows you to glue outside models into your Catalyst app.
