This chapter begins with an architecture checklist. If you had to rank the items, from most important to least important, what would your list look like? Explain your answer.

Before selecting a system architecture, the analyst must consider the following issues:
• Enterprise resource planning (ERP)
• Initial cost and TCO
• Scalability
• Web integration
• Legacy system interface requirements
• Processing options
• Security issues
Student answers will vary with regard to ranking these items. Certainly the overall ERP is the framework within which everything else happens, so it should be at or very near the top. Cost and legacy interface requirements also are very important for a successful system. Of course, there is no one single answer. As with so many issues, the answer probably is “it depends.” This task might make a good topic for a class debate.

Create a class SubstitutionCipher that implements the interface MessageEncoder, as described in the previous exercise. The constructor should have one parameter called shift. Define the method encode so that each letter is shifted by the value in shift. For example, if shift is 3, a will be replaced by d, b will be replaced by e, c will be replaced by f, and so on. Hint: You may wish to define a private method that shifts a single character.
