- You work for a software company that specializes in MFC. The company’s mission is to provide custom software development for small- to medium-sized companies. Your firm just signed a contract with the Exotic Places travel agency to develop a new reservation system. Here is the information you have been given:

• The Exotic Places travel agency employs 75 people. Thirty-nine of the employees are agents who provide customers with travel information such as flights, lodging, and cruises. These agents will also make arrangements and reservations. Twenty-five of the employees are managers. Fifteen of the managers supervise the agents. Five employees are accountants and financial managers. The remaining employees provide clerical support.
  
  
• The agents and supervisors need to use the new application as a standalone application. The accountants will need to access some of the services it provides through an application that will be built at a later time.
  
  
• It’s anticipated that the number of users will double over the next two years.
  
  
• The Exotic Places agency currently has five branch offices. Each branch office has its own database; most of these databases are MS Access. The agency is in the process of networking the branch offices together. They also hired a firm to install a center SQL Server database and migrate their data. Your application will be required to use the SQL Server database.
  
  
• The financial/accounting system that might be developed uses Visual C++. However, there is a possibility that it will be built using Visual Basic.
