Privotal Technology Research On Information System Of Oceanic Minerial Resource

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.
