After the system requirements are determined, we will enter the OOD system design phase based on UML, in which the following three articles will present the support and application of VS2010 in the design phase: Using Visual Studio 2010 from Analysis to implementation (4)--Designing message sequences using sequence diagram Using Visual Studio 2010 from Analysis to implementation (5)--Design system structure using component

The key to the processing of object-oriented problem is the modeling problem. Modeling can abstract many important details in a complex world. Many modeling tools encapsulate UML (that is, unified modeling language™), a course designed to showcase the highlights of UML. UML has nine modeling icons, namely: Use case diagram Class

What is use case The writing of case description documents is a reflection of the deep understanding of user requirements by system analysts. It is an important basis for later time sequence diagrams and actual development. It can also be used as a basis for project estimation, as well as to measure the efficiency of developers Based on UC complexity and develop

Use case identification for Requirement documents and use cases for Requirement documents Case identification for Requirement documents Case recognition is vital to your needs. Please give me some comments on this article.1. use

When drawing a use case diagram, it is important to clarify the relationship between use cases. The relationships of Use cases have generalizations (generalization), extensions (extend), and inclusions (include). Include and extend are most easily confused. Here we combine t

code.Third, the use of parametersSimilar to the alert () function, Console.log () can also accept variables and splice them with other strings:The code is as follows:Use variablevar name = "Bob";Console.log ("The name is:" + name);Unlike the alert () function, Console.log () can also accept variables passed as arguments to a string, with specific syntax consistent with the printf syntax in the C language:Copy the code code as follows:Use parametervar

There are only 3 elements in the Use case diagram, which are roles (actor), "Use Cases", "Association (Association)". The so-called "role" is what people or things use your system, that is, to do some things. For example, you go to an ATM machine to withdraw money. So in

The requirement is very simple. In the SQL Server database, store the user-uploaded Visio file, and then use the Visio Viewer to directly display the content of the User-uploaded Visio file in IE. For this requirement, we need to divide it into two parts: 1. Stores and reads the Visio file database and downloads it in Asp. Net. 2. Use the Visio Viewer provided by Microsoft and

When I first came into contact with a UML diagram, I felt pretty good about it and it was not very difficult. However, in practice, I always feel like I am painting myself. The following is a brief introduction to my new understanding of the use case recently. The Use Case

In Rose, you should use the Business actor type. Refer to the requirements described in the previous article, download the example The second step is to find out what each user is going to do, which is business use cases, an
