Hello, I have a question regards to ASP.NET 2.0 I'm developing a travel website, using a SQL Server 2000 database. This database contains COMPANIES table, which stores all travel company info. Now, I would like to store some extra info for some kinds of travel companies (not all companies), for ex only for tour operators, hotels and travel agents. I intend to design the database like this: COMPANIES (id, name, ...) TOUR_OPERATORS (id, company_id, ...) HOTELS (id, company_id, ...) TRAVEL_AGENTS (id, company_id, ...) Each tour operators, hotels and travel agents has all properties from COMPANIES table (company_id is foreign key) and some specific properties. Now I have to build a listing page, a search page, and a detailed page for all companies. I would like to know if there is a better solution to design the database and how to build the listing, search and detailed pages. Do I have to build 3 different pages for each type of companies or should I use only 1 page and use "if/else" there? Thank you very much.
