The Design And Implementation Of Prepaid Card Resource Sharing System

Prepaid cards are an important consumer payment method,which brings great convenience to consumers and merchants,thus quickly occupying a large market share.With the rapid economic development,the prepaid card business involves many fields,including membership cards,catering cards,travel cards,etc.,and is still growing rapidly.At present,Ant Group has independently developed Alipay App terminal applets for each prepaid card business,and the prepaid card business system directly interacts with each data source system.Although this development model is quite convenient when the business volume is not large,it also means that not only the amount of repeated development is huge,but it is also difficult to effectively share and utilize resources inside and outside the group.To this end,Ant Group is committed to more reasonable reuse of the resources that have been accessed,reducing the amount of development under new business scenarios,and proposes a solution for the prepaid card sharing system to manage the collection of prepaid card resources to the entire life cycle of customer applications.This thesis introduces the background of the prepaid card resource sharing system project,investigates the domestic and foreign prepaid card business systems,and briefly describes the SOFA,ZDAL,Smart Engine,Schedule,DRM,Tair and other technologies used in the construction of the system.The thesis defines the system boundary,clarifies the interaction with external systems,introduces the core business model of the system,and analyzes the functional and non-functional requirements of the system in detail,and extracts data introduction,data management,resource deployment,resource conversion,and authority Five functions of management.The overall design of the system is completed through system architecture design,function composition design,and system deployment design.The ER diagram of the business model and the structure of the database tables in the system are introduced in detail.The thesis analyzes and designs some of the subfunctions in which the author participates in detail,supplemented by necessary sequence diagrams and class diagrams for explanation,and provides implementation details,and designs test cases to complete the test.The project has been put into actual use.At present,Ant Financial has several businesses running on the prepaid card ecological resource sharing system.As the capabilities of the prepaid card ecological resource sharing system continue to improve,the development of new businesses through it will become more and more conveniently.
