2015/03/26-09:25"Declaration" Welcome reprint, but please keep the article original source: http://blog.csdn.net/yelangjueqi/article/details/45529235In Object-oriented system modeling, there are 3 particularly important relationships: dependencies (dependency), which represent the use relationships between classes (including refinement, tracking, and binding relationships) , and generalization, It connects the generic class to its special class; Asso
these things from the UML's defined building blocks, create a new building block by using stereotypes to specify these new semantics and to give a distinctive visual cue. If you want to distinguish these things from the build modules defined in UML, you can create a new build module by using the model, it is used to describe these new semantics and provide a unique visualized mark. 3. If the thing you are modeli

That " s a good thing, because it means that's can communicate your intent without ambiguity to anyone else Who knows what to read the UML. However, if you find yourself needing-express new
a thing in the UML Some of the basic graphic symbols that make up the model diagram, which represent some basic object-oriented concepts.There are four kinds of things in UML structural things (structural things), behavioral things (behavioral things), group things (grouping things),Annotational Things (note things). Two four types of things in UML (things) (1)
component marker and the component. In the component diagram, the structurePiece is a single component of the software, it can be a file, product, executable file and script, etc.such as (from the network): (10) Deployment diagram (Deployment Diagram, also known as implementation diagram or configuration diagram) The deployment diagram defines the physical architecture of hardware and software in the system to describe the actual physical device and the connection between them.

UML. enumeration type, such as Boolean and status, can be used as enumeration modeling. In the attribute column, use specific text to list (remarks are not attributes ). the enumerated type can also define operations. Note: Some languages, such as C and C ++, let you set an integer value for an enumeration literal. you can model this in the UML by attaching a
Modeling New PropertiesNew Feature Modelingthe basic properties of the UML " s Building blocks-----attributes and operations for classes, the contents of packages, and so on----is Generic enough to address most of the things you " ll want to model. However, if you want to extend the properties of these basic building blocks, you need to define stereotypes and tagged VA Lues. The basic features o
responsibilities so that each abstraction is reasonably present. D, consider the ways in which these classes work together and redistribute their responsibilities accordingly, so that no class in the collaboration has too much or too much responsibility. 3.3, modeling non-software things3.4, Modeling simple typesTo model a simple type, do the following:A, modeling

Zookeeper Modeling the distribution of responsibilities in a system Model System Responsibility Assignment Once you start modeling more than just a handful of classes, you will want to be sure that your actions provide a balanced set of responsibilities. what this means is that you don't want any one class to be too big or too small. each class shoshould do one thing well. if you abstract classes that are
something from the problem or solution vocabulary. 2. reflect a group of short and well-defined roles that can be well executed. 3. clear separation between the norms and implementations of abstract things. 4. It is understandable, simple, scalable, and adaptive. When you draw a class in UML, 1. attributes of the context of an abstract object are displayed only when the context of the abstract object is understood. 2. group attributes and operations
1. emergence of standard modeling language UML The accepted object-oriented modeling language appeared in the middle of 1970s. From 1989 to 1994, the number has increased from 10 to more than 50. Among the many modeling languages, language creators strive to promote their own products and improve them in practice. How
The development of Object-Oriented Analysis and Design (OOA D) methods has seen a climax from the end of 1980s to the end of 1990s. UML is the product of this climax. It not only unifies the Expression Methods of booch, Rumbaugh, and Jacob, but also makes further development on it, and finally unified it into the standard modeling language accepted by the masses. 1. emergence of standard
