旧机动车鉴定评估系统的设计与实现

Design and Implementation for Evaluation System of Second-hand Cars

详细分析了旧机动车鉴定评估B/S系统的体系结构和系统流程、数据库表设计。研究了系统各模块的定义与关联,并根据车辆修复与否情况,具体描述了车况技术鉴定模块的实现算法。从系统性能考虑,重点介绍了数据库的连接池技术,对其运行性能进行分析。结果表明使用数据库连接池技术的系统能显著减少Web应用程序中数据库连接的开销。该系统可替代人工客观地评估鉴定旧机动车。

B/S system structure, system flow and database tables are dealt with. Definition and relationship of each module, especially the module for technical identification of cars are studied. With system performance taken into consideration, connection pool technology of database is introduced, and its operation is analyzed, which shows that connection pool technology can greatly cut web connection cost, and the system can replace traditional method to evaluate old cars.
