ObjectiveMost of the UML describes the logic and design of the information. The implementation diagram is used to describe the realization of the narrative information. The implementation diagram contains a deployment diagram and a component diagram.Component diagram1. ConceptComponent diagram describes the main functions of a system from the perspective of software architecture. such as subsystems, classes, packages, components. Used to show the rela
In This article, we focus on UML time series diagrams, which include modeling elements in the main sequence diagram: Objects (Actor), lifelines (Lifeline), Focus control (Focusofcontrol), messages (message), and so on. First, the UML sequence diagram Brief introduction (Briefintroduction)time series diagrams (Sequencediagram) are graphs that display the interaction between objects, which are arranged in
Objectiveclass diagrams and sequence diagrams are two of the most commonly used diagram in UML. I will make a detailed summary. In many books, or Web sites, when introducing the design of a subsystem of a system, many times, a simple class diagram is given to describe the relationship between the classes that make up the subsystem. This is sufficient to illustrate the importance of class diagrams. The basic understanding of the class diagram has the f
This semester is lucky to choose to chapter Teacher's UML Fine Course, although to present only class two weeks, but the income is shallow. Although in the undergraduate contact with the UML, but do not have a very detailed understanding of it, but some of the names of some of the figures have been heard, did not delve into its function.On the recent knowledge, talk about my general understanding of
Converting a Java project into a clear UML class diagram makes it easier for us to understand the project structure and dependencies between modules. This article describes six open-source tools that can reverse engineer Java projects to UML class diagrams.
1.Eclipse MDT
Model Development Tool (MDT) provides some exemplary tools and development models based on the meta-model. It supports creating
physical design details, such as storage allocation and physical aggregation, because they are dependent on the product.
There are two aspects to implement UML model with relational database: Mapping structure (2nd section) and Mapping Function (section 3rd). The 4th section notes the extension of object-oriented to relational databases. The 5th section summarizes this article.

in a controlled manner to convey your intentions.Modeling is all about communication. The UML already gives all the tools are need to visualize, specify, construct, and document the artifacts of a wide RA Nge of software-intensive Systems. However, you might find circumstances in which'll want to bend or extend the UML. This happens-human languages all the time's why new dictionaries get published every ye
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 the project initial, analysis of the user needs of the stage, no matter how to achieve the s
Recently in the use of State mode to write a simulated Windows Calculator MFC program, the way to learn the UML diagram drawing, especially class diagram and state diagram of the drawing, here to summarize it.I. INTRODUCTION of UMLUnified Modeling Language UML (abbreviation for Unified Modeling language): is a standard language used for visual modeling of software systems.(1) in the development stage,
The first contact with UML was last year, when Liu Lijia teacher taught for us, because there was no specific project, so the UML Course is not very important, I think most people should be the same as I do UML did not give enough attention, this semester we opened the software requirements analysis This course, and let me re-contact
The key to dealing with object-oriented problems is modeling. Modeling can abstract many important details in the complex world. Many Modeling tools encapsulate UML (that is, uniied Modeling Language ).
There are nine types of modeling icons in UML:
Use case diagram
Class Diagram
Object Graph
Sequence Chart
Collaboration Diagram
Status chart
Activity diagram
Component Diagram
Configurat
Since UML (Unified Modeling Language) is often used in development, especially in the OOAD stage of software development, it is particularly important to understand and use UML. Before starting with UML, let's review the main features of OOAD and OOP.
OOAD: The process of analyzing and designing software systems based on object-oriented methodology. It includes
Summary This article analyzes the architecture mode of web applications and introduces the UML extension mechanism to model various objects in Web applications. This paper discusses the UML modeling and development methods for Web applications under the. NET Framework and applies them to a practical management system. The actual application shows that this method can reduce the development complexity, short

Every time I start to learn a new course, I will always pick up a book called the basics of ×××. Of course, the journey of a thousand miles begins with a full step. Let's first learn the basics of UML.
In the book "UML basics and Rose modeling", the UML overview is mentioned in the second chapter. The first chapter is about object-oriented. From the very beginni

UML, full name: Unified Modeling Language, unified modeling language. It is a standard modeling language for software and system development. It mainly analyzes and designs the system in a graphical manner. At the same time, UML is neither a programming language nor a formal language, but a visual modeling language.

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)
