Design And Implementation Of Depository System Based On Microservices

Since the state introduced the third-party depository system policy for securities customer transaction settlement funds,in order to meet regulatory requirements and ensure the normal development of business,commercial banks have started the construction of the third-party depository system.The management center system is convenient to connect with the three-party depository system of each bank,realize the real-time fund transfer business between banks and securities,and meet the flexible control of investors' funds.At present,the depository center business of domestic securities companies is implemented in the centralized securities trading system,resulting in high coupling between the securities depository center business and the centralized trading system.difficulties,etc.Therefore,this paper proposes a microservice-based depository center system to decouple it from the centralized transaction system.The main contents of this article include:(1)Demand analysis for the depository center system.Mainly using UML language to build the system use case model,system sequence diagram and so on,the functional requirements of the system are analyzed in detail,and the non-functional requirements of the system are given.(2)The system is designed.The overall design of the depository center system is carried out using the architectural idea of microservices,and the database design,class diagram design and sequence diagram of each microservice are given.In terms of security,based on the JWT authentication technology,some optimization schemes are proposed for the implementation process of the depository center system.(3)The system is implemented and tested.Combined with the microservice design scheme of the depository center system,the realization of each microservice of the depository center system is given,and the functional and non-functional tests of the depository center system are carried out,and the test conclusions are given.The depository center system based on microservice design has been launched,which can not only realize 7*24 bank-securities transfer service,but also solve the ever-increasing access pressure through horizontal deployment,and has flexible business expansion capabilities to cope with possible future business evolution.
