| 1. | By analyzing customer demand and the characteristics of c / s architecture and b / s architecture , one kind of pdm architecture model is proposed . on one band , b / s applies in selection , browser , services with little interactive which place is dispersed ; on the other hand , to all kind of technical information transparent evoking , edition , processing , output uses c / s pattern 本文还通过分析c / s体系结构和b / s体系结构的特点及其客户的需求,提出了一种基于c / s和b / s混合体系结构的pdm体系结构模型,一方面对各类技术信息透明的地调用、编辑、处理、输出等功能采用c / s模式;另一方面以查询、浏览、地理位置分散、交互较少的服务为主体的应用采用b / s模式。 |
