Automatic DB Update

Hi, i have managed to add tables and fields to the db. but the change only takes effect at a cleat install.
what change needs  to be done in order to have nop detect and apply changes to DB.

EF 4.3.1 includes automatic and code based migrations features. can anybody suggest where to add that change in order to be consistent with nop coding ?

this could be an option (autoupdateDB in the config file)... that can be turned off when not needed.

Have you read the docs?
