variable name and its class type in the box in the horizontal axis direction, as shown in Figure 2. This form does not include loops, conditions, and branches that are common in conventional forms. In the actual control process in the system, some assertions made during the interaction may be false. If the assertion is found to be false, all messages in the instance sequence diagram are empty, and this situation will not occur. An instance sequence diagram describes a single situation that may

(notification circuit).5. There is an aggregation relationship between the re-insured notification and the Plan library. Because the plan library can be entered in advance, and the re-insurance notification is not necessarily linked, can exist independently. In the system is manually selected from the list. Delete the re-insurance notification without affecting the plan.6. There is an aggregation relationship between the cut notification and the demand order. Similarly, a demand order can exist

that draw dots, boxes, and text strings on character-based grids that involve many Java object-oriented concepts and applications that are very systematic and comprehensive, and will quickly master UML class diagrams After you have studied them. and apply it to the actual Java application development process. To reduce the length of the code to make the program

Drawing a class diagram is a very troublesome thing. If there are tools to automatically generate class diagrams, then how good! A simple search, there really is. As (2.1) below a plugin code iris can be generated automatically.1 Plug-in installationInstallation is simple, as below find plugin, search code iris, and then install, restart as a bit, it can be used.2 useRight-click the module, click Generate Graph, and in the left tab you can find the cl

When formulating a new specific plan, the corresponding buffer time must be added in the middle of the two phases of the new learning knowledge to serve as an example. When you draw a painting without a template, you must first draw a

Turn from: http://blog.sina.com.cn/s/blog_5bd6b4510101585x.htmlWhen drawing class diagrams in Visio, we generally need to draw interfaces and implementation classes and indicate their implementation relationships . But for a long while did not realize the relationship, only the generalization relationship (inheritance relationship), how to do? In fact, it is very simple, as follows:First step:

In the UML 9 kinds of diagram, the use case diagram is the more important one kind of diagram, it is the diagram which produces in the system analysis stage, from the function carries on the analysis to the system the model, has played the strategically advantageous position function to the subsequent system development, the use case picture is good, then the system also is not far away from the success.A dynamic view of the system's functions, compos

Dragon is the first of ancient Chinese gods, the Legend of the Dragon has nine children, they have their own unique temperament, their respective roles, the benefit of the people. Like our UML, her nine children also have their own unique skills, first of all, today we are going to learn about, use case diagram--the core of nine children, her main function is to describe the user's needs, from the user's perspective to describe the function of the sys

functions, and generally adopts the verb-object phrase. 4. Determine the relationship. It is more difficult to distinguish between extension and inclusion.Include a subordinate relationship, something that is bound to happen, a naming convention, and a similar one. Extensions, however, emphasize the addition of functions that do not necessarily occur. For example: For the doctor use case, the general situation will be taken medicine, only the case of serious illness only infusion, so the medici

Recently teaching software engineering project practice, and carefully understand the next UML in the meaning of the various relationships, although a bit simple, but some concepts are often confused, written here is to deepen the impression.

communicating with others and helping to solve design problems. The important point is that the level of detail in the diagram should be only necessary to achieve the goal. You can draw illustrations with lots of decorations, but that's a way to damage productivity. Make sure the diagram is simple and clean. UML diagrams are not source code and should not be use
