【摘要】 信息技术的发展为我国大洋信息系统建设提供了支持和保证,使学科众多、结构复杂、数据量巨大的大洋系统建设成为可能。针对大洋信息系统建设方面的实际需要,就其中一些关键技术开展研究,为实现我国大洋数据信息共享和高效管理提供技术服务。在对大洋信息系统工作现状、信息内容需求、功能和非功能分析的基础上,设计了大洋信息系统的体系结构。该系统采用多层结构,包括表现层、在线系统层和数据层。在线系统包括在线信息子层和应用子层两部分;数据层包括应用子层、信息子层和数据源子层。创建了大洋数据模型,利用建模工具完成了大洋数据库设计。探讨了数据标准化处理流程。以多波束资料后处理为例,提出了一种海量数据三维建模的方法,实现了软件编程。研究了温盐剖面的质量控制方法,用VC和Matlab混合编程的方法实现了温盐剖面的可视化质控程序。阐述了基于Oracle数据库实现多种大洋标准数据自动加载入库软件的设计、实现方法以及Oracle函数创建。基于VC++和OO4O设计开发了灵活实用的CS结构的网络查询检索系统。并重点解决了JAVA开发地理地图显示站位图形、JAVA Applet与ASP网页的通信以及ASP实现大数据量数据库的查询性能优化等问题。更多还原

【Abstract】 Today, it becomes possible to setting up the oceanic resources &environment information system of COMRA which includes many subjects, complex data structure and huge data under the support and service of the quick development of information technology. In order to support the actual need of setting up the oceanic resources &environment information system,some pivotal technology are researched and the work provides technology service for sharing and managing oceanic information together.Based on its work actuality, content of information demand,analysis of its function and no-function and so on, the oceanic mineral resource information system framework has been well overall designed. The system uses multi-layer including show layer,online system layer and data layer. Online system layer includes two parts: online information sub-layer and application sub-layer. Data layer includes application sub-layer, information sub-layer and data source sub-layer. The design of the ocean mineral resource database has been accomplished with Powerdesigner . It is probed into to set up the flow of data standardization process.We present a method of constructing 3D model from huge data and implement of the program. In the paper quality control method of the profile of marine temperature and salility has been studied and implied using VC and Matlab software.It’s expatiated that oracle functions,designing and accomplishing methods of pragraming of which many kinds of ocean data can be loaded into database automatically based on oracle . Based on database,we develop a program of which a flexible and applied system of querying which is C/S structure has been accomplished using VC++ and OO4O. Three major problems have been resolved, including drawing of station chart on the geographic map using JAVA language,commucations between Java Applet and ASP homepage by Java Script, optimization of query huge data from database.更多还原
