563608 Website for Data Storage

We require a website to store information we require ability to add / delete categories, add / delete questions, add / delete answers. users then select answer and this is stored in DB we also then need to be able to search the DB for these answers. e.g. Personal info -> Age -> 30-40. we can then search for 30-40 year olds, which we can then export from excel we would prefer a modification made to oscommerce. so that instead of buying a product with attributes. buy now would be changed to update. if customer selects attribute -> age = 30-40 then when they log in next time , this is stored. need to have drop down menu for towns cities in dublin if u need more info, please ask
