The internet sales system will have a database of basic information about the CDs that it can sell over the internet similar to the CD database at each of the retail store. Every day the internet sales system will receive update from the distribution system that will be used to update the CD database. Some new CDs will be deleted, some will be added and others will be revised (such as have a new price). The electronic marketing (EM) manager will also have the ability to create and update the information. The sales system will also maintain a marketing database of materials about each CD that will enable online users to learn more about them. Vendors will be encouraged to email marketing materials that promote their CDs. the electronic marketing manager will go through the emails and determine what information to place on the web. He or she will add this information to a marketing materials database (or revise it or delete old information) that will be linked to the web site. Customer will access the internet sales system to look for CDs of information. Some customer will search for specific CDs or CDs by specific artists whereas other customer wants to browse for interesting CDs in certain categories. if customer has found all the CDs he or she wants, the customer will check out by providing personal information (including credit card ) and order information .the system will verify the customer's credit card info with an online credit card center and either accept the order or reject it . Every hour or so, the order will be pulled out of the order database and sent to the distribution system. The distribution system will handle the actual sending of the CDs to the customer; however, when CDs are sent to customer (via UPS or email), the distribution system will notify the internet sales system, which in turn will email the customer. Weekly report can be run by the electronic marketing manager to check the order status.
