Recursive Realization And Application Of The Association Class

With the development of object-oriented technology, UML model is more widely used in the software development process, because a reasonable and accurate UML models will bring great benefits for the design, implementation, development and maintenance of a software project. The relationship of class between themselves is often encountered in the Actual project, using the constraints to establish an accurate UML model and revising the model and the constraints to the relational model not only can establish a robust and stable data structures, but all so can adapt to the unforeseen changes in business rules. But in the real software development projects, we often overlook the importance of establishing an reasonable and accurate model, the use of constraints is lost in the transformation to the relational model, so there is no real ensure the accuracy of the model. So, using the UML model to establish an reasonable and accurate model and conversing to the relational model completely is the point topic of the paper.This paper research the association class in the realistic life, put forward the recursive method of establish a reasonable and accurate UML models and give the complete steps of some typical models. On the above theories foundation, case of the relationship of the one to many, produce the application of recursive technique in the tax analysis platform, demonstrate a flexible self-association data, and to the project bring great flexibility and scalability.
