Hopefully this is the right place to post this. I'm looking to create an online catalog application that sits on top of a database. The application will be accessible by registered users (manufacturers and consumers). One class of users (manufacturers) will be allowed to post data and information about parts they have for sale. The second class of users will be able to browse the parts catalog, review the manufacturers contact information and even posts a star rating (or some other simple method) of any of the parts. I anticipate that there will be a large number of manufacturers (hundreds) each having 10 or more parts. I anticipate that there will be thousands of customers reviewing the catalog. Beyond just storing the parts in the database, I anticipate that there will be some degree of flow control(i.e. prompting forms to ensure the manufacturer enters all the data necessary for each part, including a text summary/outline). I would rather not build the application from scratch and need for this application to be web based. Does anyone have advice on which direction I should head and whether there is a "quick app builder" or pre-existing system I can acquire and modify? Thanks in advance for your help, zchoose
