分布式战术数据链网络规划中的数据库设计

Database Design in Distributed Net Programming of Tactical Data Link

以分布式战术数据链网络规划为研究对象,在设计了分布式战术数据链网络规划系统结构图的基础上,重点对数据链网络规划中数据库的设计进行分析。通过分析数据库设计需求提出了设计方法,然后根据不同的部门职责对战术数据链网络规划的参数进行拆分、组合,设计了网络规划数据库的实现方案。最后,利用Power Designer软件建立了概念数据模型和物理数据模型,实现了既能存储数据链网络规划内容,同时满足分布式网络规划系统要求的数据库存储结构。

The Paper studies the distributed net programming process of tactical data link,on the basis of designing the system structure of the distributed net programming of tactical data link,it focus on the study of database designing of net programming of tactical data link. Through the analysis of database design requirements,the design method is put forward,and then according to their different responsibilities of departments,by analyzing the parameters of separation,combination of tactical data link,the net programming database implementation plan is designed. Finally the net programming database Physical Data Model（PDM） and Conceptual Data Model（CDM） is established by using Power Designer software. It can store the net programming of tactical data link content,at the same time,it meets the requirements of database storage scheme of distributed net programming.
