Abstract:

In the year of 2000, we begin to construct the Chinese Polar Science Database System(CPSDS). After analysing the factors about actuality of data management,multi resource and multi subject of the data resources, we conclude that how to organize and express the data resources is very important. Standing requirement from the users, administrative support, concise database technology and steady outlay are the key to solve organization of the multi resource. About expressing the data resources, we find that all subject data can be divided into a metadata and a dataset. Thus,it may be possible to set up a conjunction between metadata and dataset. The metadata database can be used as a "search engine" of the CPSDS.
