more and more automation, writing code more and more become a "no technical content" thing. And how to design the perfect system architecture according to the customer's demand is an important step to the success of the project. UML is actually a kind of graphical tool, it through some standardized graphics, the needs of the image to draw out, so that everyone can understand, and understand what to do, and

Today, we finally started using UML for project analysis, and found that the time overhead for using UML is not as high as we previously thought.

How do developers communicate with each other to ensure seamless collaboration between different departments? UML is the

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 storageProcess. For relational databasesSystemYou can use an object class diagram to describe the database mode and a class to describe the d

function of the system, function by the action of interaction, complete the action of nature is the object. So the outline design design is obvious: The system is divided into functional modules according to the result of requirements analysis, the module may be a class, or it may be a subsystem composed of multiple classes. A use case consists of one or more modules. So the function of the system we have described very clearly. Why the outline design, the reason has also surfaced, the further

· UML goals The development of UML has multiple goals. First, the most important goal is to make UML a general modeling language available for all modelers. It is not someone's proprietary, and is based on the general consent of the computer industry, that is, it includes a variety of major methods and can be used as their modeling language. At least, we wan

"To do a good job, you must first sharpen the tool." UML does not have any good tools to help, and often allows developers to wait halfway. What's more, developers sometimes think that UML is a very difficult technical tool for developers who use development tools that are not easy to use 」. I do not know that
