【摘要】 基于GIS平台的卫勤信息系统课题的提出是在军队全面深入的开展信息化建设的大背景下提出来的。其目的是为提高我国卫勤保障信息使用的效率、实现多种信息形式的综合应用、提供动态及时的数据信息等。本系统利用地理信息技术和数据库技术,将卫勤保障专题信息数据库与全国行政区划图、全国基础卫勤信息图相结合,为各级卫勤指挥机关提供科学有效的数据指标,实现卫勤保障数据管理的规范化、自动化。系统采用C++为编程工具,以oracle 8i为后台数据库,并充分利用地理信息系统处理地理信息和数据库系统处理数据信息的优势,以软件工程思想为基础,对每一功能进行详细分析与设计,最终实现本系统的功能。系统主要包括信息应用系统、数据库系统、标图系统、地图维护系统、系统维护等几个子系统。本系统的GIS平台的底图使用的是“军用地理交通图系统”电子地图,通过对其进行二次开发,应用索引记录、倍率记录、要素记录、级别指针、类别指针的策略,将以矢量、栅格、声音、图形、图像、文字、录像等格式存储的信息,由1:600万行政区划图数据库、1:50万全国基础卫勤信息图数据库等一系列多源数据库进行管理。以此完成空间数据关联和信息的无缝集成,组成多要素、多尺度、多时相的地理信息平台。在实体结构设计中,留有数据库连接数目、连接方式和记录集合对象的识别号等元素。在数据库中,建立地理信息与专题信息之间的联系表,具有连接方式、记录对象的唯一识别号、记录或者过滤条件的唯一识别号、图形元素类别的识别号、图形元素的唯一识别号等元素储存连接信息。通过这种方式,建立地理信息与专题信息之间的联系,实现GIS与DBMS的链接。本论文主要从研制该系统的过程入手,以软件工程学的方法,从需求分析、系统总体设计、系统详细设计等方面阐述了系统建立的全过程。更多还原

【Abstract】 To promote informatization in military, raise the efficiency of health service safeguard information in our country, carry out the comprehensive application of a number sort of information, and provide dynamic real-time data, the health service information system based on GIS platform is proposed. Utilization the geo-information technology and database, the database for health service safeguard is connected with both our national administrative map and national basic health service information map, to provide direct and complete statistic data index for all-level health service command center and realize the standardization and automatization on health service safeguard data management.In this system, C++is selected as the programming tool while oracle 8i is as the background database. By taking full advantage of the edges that the GIS disposes the geographical information and database disposes the specific information, all the functions in this system is realized by the modular design for every function with object-oriented designing method. The sub-systems divided by the systematic function mainly include information application system, database system, marker mapping system, map maintenance system as well as system maintenance.The GIS platform in this system is an independent developed system, in which by utilizing index record, ratio record, element record, level pointer as well as category pointer, the information stored in the form of vector, grid, voice, figure, image, character as well as video recording is managed by a series of polygen database system that include 1:6000000 scale administrative map,1:500000 scale national basic health service information figure database, etc in light of the research on metadata. Therefore, the seamless integration between spatial data correlation and information is realized to establish a multi-element, multi-scale and a multi-temporal geo-information platform.During the process of structure design on entity, some elements such as connection number for database, connection method as well as identification mark for recording the set-object are retained. In the database, the contact table for establishing the geo-information and specific information has connection information for element store is consisted of some items such as connection method, recording the unique identification mark concerning the object, recording or filtering the conditional unique identification mark, the identification mark on figure element, the unique identification mark concerning the figure element, etc. Through this way, the connection between geo-information and specific information is established to realize the connection between GIS and DBMS.Making use of software engineering, the content in this paper starts with developing the system mentioned in this paper, and illustrates the whole process to establish the system from the perspective of requirement analysis, system design, systematic design in detail, etc.更多还原
