antenna theory analysis and design

Some experiences in Object-Oriented Analysis and Design Analysis, Design and Implementation What I understand is the true object that exists or does not exist in real life. An obvious feature of this object is that it has many state features and behavior characteristics. For example, if a person is an object, he will

outstanding designer, his books have accumulated profound skill and are certainly not wrong!-- Visual alliance webmaster FapeThis book has a great influence on the web design and interactive interface design industries. It provides a thorough description of the content, and advocates a novel concept of web design. Zhou Yu is a very professional expert, I have kn

of some features that require your implementation at any time. Some strong project managers may reject them because they are not defined in the requirement specification, but in reality, it is often not so easy. It is even worse when we make products. If we do not consider or design the products well, the future development of the products will be buried. (Deep Mining of requirements/Digging out conceptsIn DDD, it is called metaphor/Making implicit

service layer has a GetUser method that returns a system user with a property of gender (gender), which is semantically defined for the service layer: 1-male, 2-female, 0-unspecified, and for the presentation layer, It may need to be "handsome" on behalf of men, with "beauty" on behalf of women, with "secret" representative unspecified. Speaking of which, perhaps you will also refute, in the service layer directly back to "handsome" is not OK? This is not a problem for most applications, but im

In the final analysis, there are two aspects to the design of a relational table. First, it is designed completely according to the paradigm theory. Generally, it is enough to reach the third paradigm, or you can divide it to a further level. For example, the fourth and fifth In the final analysis, there are two aspect

We have been separated by a gap for a long time, making OOAD inaccessible. 4. The four-color prototype fills this gap in history, so that we can see the hope of OOAD. 5.

also be understood, this is completely confused what is the use.To understand the role of this principle, first you need to know that an important feature of object-oriented is called polymorphism, the benefits of polymorphism can be said to be the advantage of the Richter replacement principle, polymorphism can be different subclasses as the same parent class to see, so you can block the differences between subclasses, write generic code, make general programming, To meet the changing needs.Th

good architecture should be object-oriented and composed of components );Well-managed application iteration and incremental development lifecycle. Pursuing a rational development process, understanding the key aspects of different development processes, and advocating the core concept is the key to understanding different practical processes. Processes are defined as macro and micro processes. Different from macro processes, they focus on the overall software development lifecycle, while micro

Just a while ago in a new game, about 2.x touch event found a design is not humanized problem,

Pattern (analysis pattern, Architecture Pattern and design pattern) is a topic that we discuss extensively. It is researched to improve software reuse (CodeReuse and design reuse.

Analysis and Design of Business Behavior Author: Anders JamesSynchronized from: http://www.blogjava.net/AndersLin/archive/2006/12/23/89648.html Complex business behaviors are generally seen as a collection of complex rules and processes. The basic solution relies on the basic way of thinking: decomposition structure.The first element of decomposition is object-oriented cohesion. Usually the object-oriented

mistake, you need to try to prove it. (56) If you use inheritance 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 design, make sure that no base class is actually a derived class of another base class. (58) In

The role of Design Pattern in the design and development of object-oriented systems is like the role of Data Structure in process-oriented development. The Analysis and Design of object-oriented systems are actually two points. One is high cohesion, but low coupling ). This is what our software

analysis to implementation (6)--Implementing system components using logical Class diagram Component diagrams In Ooad, we use component diagrams to provide interfaces for systems and behaviors. In theory, a component should be able to demonstrate a single major functional module in the system, such as Web Services,. NET, COM, CLR, or user interface (UI). A component diagram can help us to understand the
