Research And Key Technology Realization Of Railway Enterprise Annuity Information System Based On Micro Service

In view of the currently problems,for example,sharing information between the railway enterprise annuity management and the social security system is difficult,applying data is not standard,acquiring data from the annuity institutions is laggard,supervising and managing the process of investment and operation are weak,updating the information system is complex,reusing and maintaining it are poor,which has restricted the requirements of digital transformation of railway enterprises.Facing the complex annuity management and the huge annuity fund investment supervision,this paper designs and develops the railway enterprise annuity information system under the background of annuity information sharing,business process integration and whole-process information management.This paper construct railway enterprise annuity information system based on micro-service architecture.After fully studying micro-service architecture technology,micro-service authentication and authorization technology,and rule engine technology,the micro-service architecture is designed.On the basis of the concept of research-driven design,daily operation compliance,investment tracking and evaluation system,and investment performance evaluation system,the actual business requirements and overall business process of annuity management in railway enterprises are analyzed.The enterprise annuity strategy is designed by domain-driven design,the system's micro service split and domain model is established by context mapping analysis.This paper designs the system architecture,logical architecture,technical architecture,interface and function;describes the implementation process detail of enterprise annuity investment operation supervision,data interaction with annuity institutions,authentication authorization,log monitoring,payment standard implementation,data storage and other key technologiesThe system has been put into operation and is running stably,which improves the management efficiency of the daily trust of enterprise annuity,realizes the whole-process monitoring of information flow and capital flow to facilitate the supervision of investment operation,and realizes the requirements of data processing timeliness and security with annuity management institutions,improves the ability of horizontal expansion and rapid update.
