基于WEB技术的协同数据库分布交互仿真研究

摘要
当前协同数据库分布交互相关方法存在用户访问满意度低和数据同步性能差的问题,提出基于WEB技术的协同数据库分布交互方法。以WEB技术在数据交互中应用分析为依据,构建WEB技术下协同数据库分布交互框架。数据库交互框架中的表示层主要负责将交互响应结果提交给用户。业务逻辑层主要责任为处理客户端提交的请求及联系服务层,完成业务逻辑层运算;服务层主要负责业务逻辑层的数据供给。分别分析交互过程中数据库信息分类、WEB适配器和数据同步更新等关键技术,为数据库分布交互提供技术支撑。依据交互框架和关键技术,给出数据库交互流程:初始化交互界面,数据库发布对外提供网络服务信息。用户提交交互申请并认证用户身份;用户检索所需资源,应用服务器绑定用户请求并获取接口信息,将用户所需信息数据传输至服务接口。用户接收交互结果,完成一次数据库分布交互。实验结果表明,上述方法实现后用户满意度高、数据同步更新性能强,具有实用性。
At present, the relevant methods of collaborative database distribution interaction have the problems of low user access satisfaction degree and poor data synchronization performance. In this article, a method of collaborative database distributed interaction based on WEB technology was presented. Based on the application analysis of WEB technology in data interaction, the distributed interaction framework of collaborative database based on WEB technology was constructed. The presentation layer in database interaction framework was mainly responsible for submitting the interactive response result to the user. The business logic layer was mainly responsible for processing the request submitted by the client and contacting the service layer, and thus to complete the operation of business logic layer. The service layer was mainly responsible for the data supply of business logic layer. Respectively, the key technologies such as database information classification, WEB adapter and data synchronization update during the interaction were analyzed, which could provide technical support for database distribution interaction. According to the interaction framework and key technology, the database interaction process was given: the interaction interface was initialized, and the database release information provided external network service. Then, the user submitted the interaction demand and authenticated the user identity. Meanwhile, the user retrieved the required resource, and the application server binded the user request and obtained the interface information. The information required by the user was transferred to the service interface. Finally, the user received the interaction result and completed a databasedistribution interaction. Simulation results show that the proposed method has high user satisfaction degree, strong data synchronous update performance and practicality.
