On the foundation of expatiating the importance of constructing optical database , the realizing way and main technologies of constructing whole database are put forward in this thesis ; optical database model is designed which is followed the database design principles ; the input program is developed ; some data mining technologies which maybe used in data analyzing are advocated 本论文在阐述了建立光学数据库重要性的基础上，提出了进行数据库整体建设的实现路线和主要技术手段，并遵循数据库的设计原则进行了光学数据库模型设计，开发了数据录入程序，提出了几种在光学数据库的数据分析中可能用到的数据挖掘技术方案。
Then it constructs three layers frame in dnc workstation according as this model and deeply discusses the key technique . in designing for facility network , the paper study method , frame and communication soft in connecting , network between numerical control equipment and host computer of dnc . based on com component , the paper brings forward designing method for the system of reamer management system , file management system , equipment management system in dnc system and gives an example for the realization of data copy component and data query component in reamer administration 在车间局域网的dnc系统设计中，采用了b s网络通信模式，然后依据此模式构建了dnc工作站的三层体系结构，并对其中的关键技术进行了深入的探讨；在基于设备网的dnc系统中，对数控设备与dnc主机之间的网络连接方法、结构以及通信系统软件的设计进行了研究；在com组件技术的基础上了提出了dnc系统中的刀具管理系统、文件管理系统、设备管理系统的设计方法，并针对刀具管理系统中的数据录入、数据查询组件的实现举例说明。
This paper using maplnfo geographic information system tool , ms access database system and vb programming language , combining plentiful professional knowledge , through integrated second development , deeply analyses processing technology of several typical urban road traffic information in gis , designs and realizes data write , data maintenance , data inquire , analyse and process , data print and so on , processes spatial data and attribute data of urban road traffic information correlative , and according to the need of geographical information system , divides all the urban traffic management business into four systems , include traffic basic facilities management system , public transit management system , traffic survey management system , traffic order management system , every system has several sub - systems , thus dctailizc urban road traffic management business 本文选择mapinfo地理信息系统作为开发平台，结合microsoftaccess数据库工具和visualbasic编程语言，利用丰富的专家知识，经过集成二次开发，深入分析了几种典型城市道路交通信息在地理信息数据库中的处理技术，设计和实现了数据录入、数据维护、数据查询、分析处理、数据输出等功能，对道路交通信息的空间数据和属性数据进行了一一对应的处理。并进一步提出将公安交通管理全部业务按信息化系统的需要划分为：交通基础设施管理系统、公共交通管理系统、交通调查管理系统、交通秩序管理系统四个系统，每个系统下面分为若干子系统，从而细化了城市道路交通管理的业务。
Based on the architecture of the as / 400 server , section 3 also puts forward based develop solution of described the construction of the flight arrangement information management system develop for both of hardware platform , software platform and development tools . section 4 discussed the implementation of the applications software , in details . section 4 also particularly introduces the design and realization of the flight data input module , the flight aided arrangement module , the sold seats computation module , the important data maintain module and common forms generation module 本文首先介绍了管理信息系统的基本概念；然后分析了航班调度信息管理系统的功能需求，比较了其几种可行的实现方案，提出了以as / 400为服务器的系统总体开发方案，论述了硬件设计选择和软件总体设计和模块划分；接着，介绍了软件开发环境和工具，并对航班数据录入、航班辅助调整、销售座位数计算、重要数据维护、常用报表生成等各个软件模块的设计与实现进行了详细的介绍；最后，说明了对开发所得系统进行测试的结果以及今后改进的构想。
