The system realizes electronic centralized information management of all budget projectts. Based on budget management regulations of Lanzhou Bureau, a standardized, transparent, and traceable budget project application and approval process has been designed. The rule engine Drools is used to implement a configurable budget project management process, making budget project management work faster, more efficient, and standardized, and enhancing the flexibility of the management process and the maintainability of the application program. The system uses the distributed object storage system MinIO and the online file preview tool kkFileView to achieve centralized management of project attachment documents and secure preview and download functions, ensuring that project attachment documents are tamper proof and strictly audited. Integrated with a powerful chart drawing engine, it realizes the visualization of budget project data and various customized charts, providing intuitive and convenient project execution monitoring and abnormal incident warning functions, providing a powerful technical tools to improve the efficiency of budget project management and strengthen risk control in railway enterprise.
