Formulize, based originally on Formulaire, may also suit your needs. It is focused on searching, sorting and reporting on the data in the database, rather than sending e-mails.

P.S. Snow - I saw your comment on Formulaire in the module repository, and FYI Formulize has an export to csv feature that may be more like what you are looking for. Unfortunately, there is no import mechanism to take your forms and data between the modules, but the data structures are not that different and with a bit of work it would be possible.
