Application And Research Of UML Modeling In Online System Of Motoring Pollution

The problem of environmental pollution has been a major problem plaguing the way peoplework, lives and learning. More and more people pay attention on monitoring of pollutants. Thesystem of monitoring pollution has become an effective way for these problems inenvironmental pollution. The development of online system of monitoring pollution is lackof the modeling process. The UML modeling language is object-oriented, and we can recognizeobjects in the system directly, and can ensure that the system’s objects consistent with theobjective things. System analysis can be directly and objectively described, the eventualestablishment of the system can meet the actual and basic requires.This paper analyzes the function of the online system of motoring pollution anddiscusses how to use UML tools to create online system of motoring pollution. With the help ofUML-modeling tools, we can create the class model, interactive model and statemodel. Use-case analysis is the basis of system modeling. According to the system’s function, wecan describe the use case diagram of the different actors. Class diagram of the design andimplementation need to be based on the system model with the help of Magic-draw UML.We candraw the precise class diagrams and object-oriented systems. The design of the class is veryimportant and we describe each class’s member variables and interface functions in detail,including the relationship between various classes. Due to the different attributes of the class, wecan draw different state diagrams. Interaction diagrams include sequence diagrams and activitydiagrams, which are very different.The system’s development process follows the UML modeling process, from requirementsanalysis to logical design and physical implementation, reflecting the formal process of softwaredevelopment. During the development process, UML modeling tools not only provide theguidance for the software development, but also avoid the enough work. More importantly, theycan improve work efficiency, meanwhile, improve the software development process. Modeling ofthe system step by step, we can establish the norms of the online system of monitoringpollution, which lays the foundation for the future research work.Finally, we summarize our work and find out what we continue to improve in our work.
