面向农业软件开发的构件库研究与实现

农业应用软件开发中存在重复建设、开发效率低下等问题,为此该文研究了农业构件库构建技术,根据农业构件的特点,提出了农业构件分类模型。对农业构件库的发布、检索、审批、存储、评估以及反馈等关键问题进行了详细分析,给出了构件库的具体方法。在此基础上基于MVC框架模式,开发了农业构件库系统。最后,进行了应用系统开发试验,试验表明构件库技术有助于快速搭建应用系统,提高软件开发效率。     

Application of Changing Dimension and Classifying Power Management to Large-scale MIS

While large-scale MIS is being developed, what relation schema and power management system to set up greatly influences its initial development and later use. First, to solve the setup of relation schema concerning constant change in the attribute of an entity, a changing dimension based on the relational theory in tradition has been used for the setup of relation schema with a wide adaptability; second, to achieve effective power management where there are different standards for business classification on account of too many users and frequent alteration, a classifying power management system has been adopted for the realization of classified self-management model, making the whole system compact and flexible.     

基于XML SCHEMA的异构生物信息集成研究

在后基因组时代,常有大规模的生物数据产生.这些生物数据的存贮形式各不相同,特别是与一些特定研究领域相关的数据,与其他数据的存贮形式差异较大.随着数据源的不同,数据模型的规范也不相同,同时,基于这些数据的应用服务各不相同.针对目前生物信息学中存在的异构生物数据现状,提出了一种基于XML Schema集成异构生物信息的方法.
