IDP（综合数据业平台）数据持久层和内容管理的设计与实现-计算机科学与技术专业毕业论文.docx

Hibernate、JCA(Java Hibernate、JCA(Java Cryptography Architecture)、JCE(Java Cryptography Extension)等技术。另一方面也提供了一套数据对象与 设计模式的组合架构。本章还讨论了基于NFS文件系统与基于数据 库系统存储内容资源在IDP系统中的性能优劣。第四章以内容管理系 统中的关键模块为例，介绍了内容存储管理与内容适配模块的详细设 计。其中内容适配模块中又包括三个方面：一是内容转换的架构和 JIMI(Java Image I／0 API)等内容资源转换技术；二是基于PPG(PUSH Proxy Gateway)的WAP PUSH发送模块；三是基于UAProf(User Agent Profile)等信息的终端信息采集模块的设计。最后，论文的第五章以 彩信资源的管理为例，介绍了彩信资源是如何基于IDP系统的数据持 久层与内容管理系统来进行管理。其中首先介绍了彩信增加的业务流 和数据流。而后，又以彩信下发为例，进一步阐述数据持久层设计对 上层业务的性能提升，并介绍了彩信下发中使用的LRU(Latest Recently Used)群发缓存策略。第六章是本文的一个总结与展望，指 出了技术发展和IDP系统中数据持久层与内容管理的下一步发展方 向。 关键词：数据业务，数据持久层，内容管理，JPA，NFS，WAP PUSH DESIG．N DESIG．N AND IMPLEMENTATION OF PERSISTENCE IAYER AND CONTENT M A NAGEMENT SYSTEM IN IDP(INTEGRATED DATA—SERVICE PLATFORM) AB STRACT Nowadays，Mobile operators are changing from the mobile communications specialists to mobile information specialists．With the transform of mobile operators in the role of strategy,the entire value—added services market is changing．Mobile operators have already started to integrate market and probe self-supporting service．According to the present trend，an integrated data-service platform will be the direction of the development of mobile data services．Different types of value-added data services can be developed quickly in this platform．There are common data service templates in this platform．The platform is able to provide unified management for all kinds of resources (such as audio，photos，text messages，etc．)，with a unified content management functions．And it also has the functions of operational role (as CP(Content Provider))management．Under the current status of mobile data services，we introduce an integrated data platform(IDP)．The IDP focuses on mobile user groups，fully integrates community resources， and provides many kinds of value—added data service to mobile users such as Life-Service，Entertainment—Service and SO on． Integrate Data—Service Platform(IDP)is an open，modularized， standardized，layered application platform，many m
