DESCRIPTION

The session data is preserved by using DBI.

'Egg::Model::DBI' should be able to be used for use.

And, Egg::Helper::Model::Session. 'Base::DBI' is added to startup of the component module that generates.

'Base::FileCache' in this systemIt is not possible to cooperate and delete it, please.

Moreover, it is necessary to load Store system module to treat the session data appropriately.
