object oriented analysis and design ebook

In Ood (object-oriented design), abstract classes or interfaces are often used, "note: in C + +, there is no concept of interfaces, only abstract classes, and both exist in Java." In the process of use, there may be many people think that the interface and abstract class is similar, and then think of course that can be completely replaced with each other. In fact

Service-oriented analysis and design principles Author/OLAF Zimmermann, pal krogdahl, Clive Gee Experience from the initial Service-Oriented Architecture (SOA) Implementation Project shows that, for example, object-oriented

1. MVC(1) Model: The application object;(2) view: the screen presentation of the model;(3) controller: the way the user interface reacts the user input. 2. View and model: decouple views and ModelsEstablish a subscribe/policy protocol between views and models.Subscribe: update or create views without rewriting models.Required Y: changing models will have y views that depend on them. 3. View and view: compositeview: implemented as a complex view contai

focused on the use of "skills." And, in combinatorial aggregation, two classes are partially related to the whole, and combinatorial aggregation can be composed of the skills of multiple classes. Only single inheritance in C # and Java.The principle is not to tell us not to inherit, all use combinatorial aggregation, but at the point of "reuse", we prefer to use combinatorial aggregation.Common problems of object-

"Multiple dedicated interfaces are better than a single common interface. "This principle is the natural result of a single duty principle for interface design. An

Seven principles: Open and close principle, Richter substitution principle, dependency reversal principle, synthesis/aggregation multiplexing principle, Dimitri rule, interface isolation principle, single duty principle.The open and closed principle is the cornerstone of object-oriented reusable. The other six principles are instruments and tools.Details of the rules (reproduced in this section)http://kb.cn

in object-oriented design, ask yourself two questions: (1) is the derived class A special type of the thing it inherits from? (2) is the base class part of a derived class?(57) If you find multiple inheritance relationships in an object-oriented

1 OO design principlesThe use of object-oriented analysis and design ideas, for us to analyze and solve problems to provide a new way of thinking. After we get the demand (omit Ooa, complete later), the next question is: How to object
