Based On J2ee Architecture, Small And Medium-sized Hospital Management Information System Design And Implementation

At present, the medical cause develops rapidly and the small and medium hospitals'scale grows faster in China.But how to apply information technology to improve the daily management level and the daily management efficiency has become the urgent task of the small and medium hospitals.With advanced computer technology, the thesis designed and implemented the small and medium hospital management system to improve the management quality and the work quality, and to make an effort to improve the small and medium hospitals'competitiveness.Based on the business processes and business needs, the network topology and the system architecture are designed. With J2EE technology, the system is designed and developed.The system architectur is designed using MVC pattern and DAO pattern. The struts framework achieves the MVC pattern. The javabeans achieves DAO pattern. By using of the features and benefits of the MVC pattern and the DAO pattern, the system works more better and more efficient.The system features are:First,using the MVC pattern, the system lows the dependence between the layers and makes business logic easy to reuse.Second,using Struts framework to achieve MVC pattern, the system has a clear structure.Third,using the DAO pattern, the system achieved the separation of the business logic and data storage,achieved the separation of business logic and data access, and achieved data abstraction.Finally,the system used the role-based access control technology to reduce the complexity of authorization management and reduce administrative overhead.The thesis completed the system design and development of the main module, covering all the management functional modules in the small and medium hospitals.The system achieved information management in the small and medium hospital,reduced the labor intensity for medical personnel, improved work efficiency, service quality and medical standards, made patients enjoy full, high-quality, convenient, fast, scientific, modern medical services.
