基于Web的水稻品种审定系统的设计与实现

Design and implementation of rice variety identification system based on Web

为了实现水稻品种审定业务流程网络化,设计了基于Web的水稻品种审定系统.采用基于组件的三层拓扑结构模式和Struts框架,利用工作流技术思想和统一建模语言(UML)构建系统模型.模型通过用户输入的登录信息与后台数据库中的姓名和身份证信息比对来解决身份认证等问题,并运用改进的角色权限分配原则、加密类MD5code、代码访问信任策略设计系统的安全机制.

A rice variety identification system is developed,in which the business process,based on Web,is implemented firstly.Structure of the system is built based on the model of component-based three-tier topology structure and ＂Struts＂ framework.The system model is constructed with workflow technology and unified modeling language（UML）.To solve the problem of identity certification etc.,the system compares the login information input with the name and identity card of database.The mechanism of security is constituted on the rule of role-based access control,MD5code of encryption class and code-accessed trust policy.
