DAO interface definition

func NewDAO

func NewDAO(conn Conn, driver string, prefix string) DAO

NewDAO returns a reference to a newly created struct that contains the necessary information to access a database. Prefix parameter is used to specify a prefix to avoid collision between table names in case this DAO accesses a shared DB: it thus will be an empty string in most of the cases.
