摘要
利用软件即服务(SaaS)模式中软件服务和多用户租赁的特点,提出一种动态信息门户开发框架(dynamic information portal framework for SaaS model,DIPFS),替代传统ASP模式开发动态网站,以满足现代大数据规模上的增量需求。DIPFS的数据存储服务采用SaaS第四级成熟度设计,支持面向集群水平方向的自由扩展;从领域工程的角度出发,用eJackson图描述网页构件的特征模型,完成DIPFS核心的页面生成功能;以一个动态图片部件的实现过程为例,描述DIPFS提供的共用软件服务并展示生成页面的最终效果。
Using features of the software services and multi-user lease in service （SaaS） mode ,a dynamic information portal de-velopment framework was proposed to replace the traditional ASP model to develop dynamic websites ,in order to meet the incre-mental demand in this big data age .DIPFS data storage service adopted the fourth SaaS maturity design to support the expansion of the cluster in the horizontal direction .From the perspective of domain engineering ,eJackson graphics were used to describe the feature model of web component .Then system generated pages ,which was the DIPFS core function .Finally ,an example of the implementation process of a dynamic picture part was given ,the DIPFS software services provided were described and web screenshots as generation results were displayed .
