Define Booch Method

Process-oriented object-oriented UML & RUP &

In fact, process-oriented and object-oriented software technology is, we have summarized the general structure of process-oriented analysis methods, often using the diagram DFD, ER model, UC matrix, etc., are summarized in object-oriented inheritance, encapsulation, polymorphism and other specific technologies, in fact, all the technology, but people use different methods to understand and describe the world, and used tools. I am the target object-oriented programming is never re-used, on the contrary, for me, the object provides a way of dealing with complex issues, this problem can be traced back to Aristotle: You make the world as a process or the object? Before the rise of movement in object-oriented, process-centric programming, such as structured design methods. However, the system has reached beyond the complexity of its processing power pole. With objects, we can raise the level of abstraction to build through the larger, more complex system — I think that this is the true object-oriented programming movement's victory.

To sum up, object-oriented theory of knowledge that can help us build a more complex system to explain the increasingly complex real world. Process-oriented, that the world is not all that isolated, they are closely linked to each other, are indispensable, mutual influence, the role of forming a strict causal relationship with the little systems, more large-scale systems composed of small systems, the links between all the small systems are close and inseparable.

The world as a process of this method itself assumption that the process is stable, so we have the basis of the analysis, all of the work rely on the process. All aspects of the process has a strict causality. Unfortunately, this world is not static, changing all the time in, so the system relies on the causal relationship becoming increasingly vulnerable. Process-oriented face too many difficulties. The world has been difficult to cope with the complexity and frequent change something. In fact, process-oriented approach is not incorrect, but because too many factors constitute a system, and take all possible factors are taken into account all of the causal relationships are clear, and then simulated the process is too difficult, our energy is limited, computing power is limited, so for the process on this complex world has become helpless.

"With a hammer may not be able to become an architect" to learn object-oriented language is necessary, but not the first to understand the object thought of is the key.
