The Design And Implementation Of The BCE General Finance System

This article introduced the background, design and implementation of the bce general finance system.The general finance system is designed for the financial to support their daily operation. This system belongs to the category of financial software applications, so we focus on the security of data and the standardization of operations when designing the general finance system. The requirement of BCE finance system changes frequently. Therefore, we think that to react rapidly to the changes of requirement is one of the most important design principle. Overall, the general finance system must be both flexible and rigorous.We chose a layered architecture design finally. The finance-core module in the bottom layer, mantaining the data of accounts is a core module of finance system, and changes hardly. The finance-admin module in the middle layer, handling the general business logic of finance system, can be chaged frequently reacting to the changes of requirement. In addition, we designed a osp-finance module, providing a website interface for financial staffs. All those modules have samilar structure, based on Spring Boot framework and using MyBatis to access database. The interaction between modules are via RESTful service api.The Spring Boot framework is used to develop this system, and apache maven is used as the build tool of this system. We also chose the H2 engine as the database while testing this system.After the general finance system deployed, financal staffs can query and analyze the accounts of users by raising and handling finance workflow on it. The general finance system increased the efficiency and reliability of business, and brought benefits to the company.
