摘　　要：以Goole App Engine(GAE)云平台为切入点,对其中的数据存储技术(BigTable)做了深入的分析和研究.在此基础上利用GAE所提供的开发工具,基于面向对象的思想,采用Struts+Spring+Jsp的开发框架,使用了Google App Engine开发技术,设计并实现了人事管理的原型系统.通过对原型系统的开发和云端的部署及测试,分析了原型系统的性能.在此基础上,提出了在云平台上开发SaaS软件或进行数据迁移需要探索和解决的问题,认为在云计算发展的初期,在云端只适合开发部署基于请求-应答的高伸缩性的不涉及多表关联的简单互联网应用系统、简单存储系统及需要高效性计算的智能决策系统.This paper starts from the Google App Engine (GAE) and makes deep analysis and study of its data-storage technique (Bigtable) .And on this basis ,a prototype system is designed and implemented ,which Based on the object-oriented thought ,using the Struts + Spring+Jsp development framework ,using the Google App Engine development technology .By developing the prototype system as well as deploying and testing of the cloud ,we analyze the performance of the prototype system .On this basis ,put forward the suitable for the characteristics of SaaS software developed by cloud platforms and the problem should pay attention in the development process and present the author's view that ,in the early stages of the development of cloud computing ,in the cloud is only suitable for development and deployment of high scalability based on request/reply does not involve multiple tables associated with simple Internet application system ,storage system and the intelligent decision-making system need high efficiency calculation .
