It is enough to look at the UML diagram drawn by others occasionally. Dramatically, I have seen the most UML
This essay is good, the use of PHP to explain the UML (or conversely) can be said to be an innovation, through this article, I also found a good station: www.phppatterns.com. The translation of the UML terms comes from the Unified Modeling Language User Guide, which I am looking at. UML (Unified Modeling Language, Unified Modeling Language) is a mechanism for rep

1. Introduction to UML UML (Unified Modeling Language) is a visual modeling language that is well defined, easy to express, powerful, and universally applicable. It integrates new ideas, new methods, and new technologies in the software engineering field. Its scope is not limited to supporting object-oriented analysis and design, but also supporting the entire process of software development starting from r
Start learning the UML modeling language, starting with the use case diagram. Modeling Tools Select VisioThe use case diagram describes the system functions understood by the participants, the main elements being use cases and participants, and helping the development team to understand the functional requirements of the system in a visual way. At this time in th
From http://www.umlonline.org/school/thread-34-1-1.html Let's take a look at the sample image? The use case diagram looks pretty good. There is a little person in the diagram, And the use case diagram is a little bit of a feeling of reading the doll book.The use case map looks nice and looks nice. What is it?The use case
UMLThe use case diagram is a very useful graph. In demand analysis, it can free people from the heavy documentation, in addition, it prompts people to express their meaning more accurately and intuitively when making demands. Common languagesThe word is often unable to express a thing clearly. At this time, it needs to be expressed in other ways. The example graph is a good method, of course, the use case diagram
Speaking of the package diagram, let's take a look at the package 1. What is a package? A package can be directly understood as a namespace and folder, which is used to organize the encapsulation of graphics. 2. What is the role of the package? Logically modularize a complex Graph OrganizationSource code 3. When will the package be used? From the perspective of object-oriented software development, classes are th
The existence of UML time series diagramIn the previous article, the UML class diagram was recorded, and the class diagram was used to describe the classes needed in the code and the relationship between them, and the whole program framework was displayed in front of us, like a painting, there are some people with wate
UML class diagram Using UML class diagrams, we can express the static content of classes and their relationships. In the class diagram, we can show the member variables and member functions of the class, as well as the inheritance and reference relationships between classes. In short, we can depict all source code-leve
adduser () method can be defined as public Boolean adduser (userdto user). In the iuserdao method, adduser () the object of the userdto type is used as a parameter, so there is a dependency between iuserdao and userdto. Through the above analysis, the instance reference Class 1 is shown in Figure 1: Figure 1 Reference class diagram of the registration function Note:When drawing a class diagram or other
I,UML diagram and code representation of class-to-class relationships The relationship between classes plays an important role in understanding object-oriented objects. I was often asked this question during interviews. Here I will introduce it.There is a relationship between the class and the class:(1) Generalization)(2) Association)(3) Dependency)(4) Aggregation) UML
In my study of design patterns, I used UML for modeling.At first I was not too clear on the understanding of the various relations, on the internet also searched some information, now on the class diagram of these kinds of relationships: dependency, association, aggregation, composition, generalization, implementation of a description.First of all, we need to know two points:1. Order of their relationships:

UML OverviewThe role of 1.UML: a complex problem decomposition B realizes the visualizationUML is created by rational company 2.UML is what: is a language, has its own standard expression rules, is an analytical design language, is also a modeling language 3.UML including five large views, 13 kinds of Figure five
After reading the UML video, I want to start drawing documents. I don't know how to start! Let's summarize the nine types of diagrams and relationships in UML, and then start with the document. First. The nine types of UML diagrams are: use case diagram, class diagram, obj
The object class diagram of UML can be better usedDatabaseModeling. Traditional E-R diagram only focus on data, while UML object class diagram not only on the data, but also on the behavior modeling, these behavior in the physical database is designed as a trigger and storag
. "When" is the answer, that is, how the development work is scheduled; 4. "Who" means that some development (or maintenance) work is intended to be done by "who? "· 5. "How" means how certain requirements are met; 6. Why? The above is the relevant content of the soft work document. Let's take a look at the relationship between the UML diagram and the document below: First, the
closely linked.The subsystem in UML uses a rectangular border to represent a subsystem that can write a description of some of the systems: (5) Relationship A relationship is a relationship between a participant and a participant, a use case and a use case, a use case and a participant, usually divided into four types: association, generalization, inclusion,Extended.The following four relationships are included in the standard use case
describe complex program logic or multiple parallel transactions. A collaboration diagram is a graphical representation of the related interactions between objects, and can also have hierarchies. Multiple objects can be used as an abstract object, through decomposition, using the lower-level collaboration diagram to express the collaboration between the multiple objects, which can alleviate the complexity
name that differs from the other package. The name of the model package is a string that can be divided into simple names and path names .Simple name: refers to a package that contains only a simple name.pathname : Refers to the name of the outer package that the package is located in as a prefix.3, the role of package diagrams:Package diagrams can describe the requirements, the design of the high-level overview, package diagram through the rational
