摘要
介绍了长江河道信息服务系统二维信息查询模块的主要功能与特点。该模块将联动、缓冲区等多种思想和技术应用于查询系统中,不仅使系统的查询功能简单化,同时也很好的解决了用户对于设计洪水位、岸线利用等信息的实时性、随意性查询的需求。使得系统在满足基本属性查询的同时,又能通过一些专用菜单以及创新性的功能设计,对存储于数据库中的信息进行整合利用,具有便捷高效、功能全面、针对性强等特点。
Main functions and characteristics of the 2-D information inquiry module of the Yangtze River Channel Information Service System are presented in this paper.The module applied several ideas and technologies for interconnecting and buffer area to the inquiry system,resulting in not only simplifying the system's functions,but also satisfying user's requirements of real-time and random information inquiry about design flood level,river bank utilization,etc.The system can meet the requirement of inquiring into basic attributes and integratively utilize information stored in the data base through some specific menus and creative function designs.This system has characteristics of high efficiency,all-round function,strong applicability,and is convenient for its application.
