I started programming using C# a few weeks ago. I would like some information about designing,making the code of a vidoe rental system. This system has to have a list of clients, list of dvd's for rent, list's of vidoe tapes, adding new clients and dvd's , video tapes. Consists of four different prices eg: new releases: $2 ... then the owner change the price to a lower one. For now I do not want that the system uses any files to store.
