After market research, this paper conceives that first to integrate sellers and the manufactures of the cosmetics fields, with the increase of the amount of users, it will extend to other fields.E-commerce APP adopts the idea of software engineering to guide the whole process. From the requirement analysis at the start, to the technology research, detailed design and implementation, until the test, and obey the requirements of each stage in the software engineering process, strictly control the input and output of every stage, thus ensure the controllability of the quality, progress, costs and risk, enhance efficiency and also ensure the stability, reliability and maintainability. APP adopts the idea of modularization and thought of object-oriented. Inside the module, it adopts several design patterns such as MVC (Model View Controller), singleton, factory and so on, which improve the reusability of modules, reduce the coupling between modules, and that will make it easier in the later maintenance and expansibility.This paper finally finish the design and implementation, such as product display function, add or remove from the cart function, pay function, share function and so on, basically meets the requirements of e-commerce.
