In this chapter, we look at how to model system dynamics, focusing on two aspects: interactions and behavior. An interaction model shows a set of actors and objects interacting by exchanging messages. A behavior model shows how an object or system changes state in reaction to a series of events.

In this chapter you will learn about the following: Characteristics of users that every software engineer should understand; various ways of working with users to ensure that a software system has both the required functionality and the required usability; some basic principles for the design of sim[r]

In the previous two chapters, you learned about technologies that software engineers need to master before developing applications. Now, we can start thinking about the particular problem we wish to solve. We will first put effort into understanding the background of the problem, a process called do[r]

In this chapter you will learn about the following: Frameworks, reusable software subsystems that implement important facilities which many applications can use; the client–server architecture, an important way of designing programs in which the software is divided into two main parts: a client prog[r]
