Develop a deployment diagram for the following description of a Face book application. The Face book platform is available for entrepreneurs to develop applications for use among all Face book users. A new application is being written that allows Face book users to send gifts and greeting cards to their friends. (These are real gifts and greeting cards, not just electronic images.) The application running within Face book is on its own server and has its own database of information, which includes a list of gifts and cards that have been sent or received. The actual retail store of gifts and cards to send must be located on a different server because it is part of a regular Internet sales storefront. This storefront maintains the database of inventory items to sell, and collects credit card payment information.
