On the use of traditional software development methods in the actual software development process

There are two main types of traditional software development methods: process-oriented and object-oriented, and they are actually complementary to each other in actual software development. The following are the specific practices:

In the process of developing software with the process-oriented approach, the requirements are phased in to analyze system functions by establishing functional models. The modeling tool of the functional model provided in process-oriented methodology is a flow graph, which can be used to model the use case diagram provided in object-oriented methodology, and the results are very good; design the algorithm for each module in the detailed design stage of the process of developing software with process-oriented methodology. In this case, we can borrow the activity diagram provided in the Surface object methodology to design the algorithm. The whole design phase of developing software with object-oriented method does not need to build software structure, but if we use the idea of process-oriented methodology, we also add software structure diagram at this stage, which can make the system structure more distinct and the design idea clearer. In the detailed design stage of developing software with object-oriented method to determine the algorithm of the service in the class and the algorithm of the association between the classes, we can draw on the graphical tools (flowchart, n-S diagram, pad Chart), table tools (decision table, decision tree), language tools (PDL language) provided in the method of the surface image process. To the design of the algorithm, so that the algorithm to achieve readability, maintainability is very good.
