Design And Implement Of Web Service-Based Data Product Processing Service System

Sun-Earth space environment is vital to human survival and development, but human knowledge about space environment is still in its infancy. A series of space weather disasters make people come to realize the importance of space weather research. Some countries have launched a series of space weather satellites, to observe space weather. However, A variety of data,with the characteristics of huge data amount,rich metadata information,diverse data formats,is generated by the space weather instrument in process of observation and data processing. Faced with these complex datas, it is hard for people to find the laws of space weather behind these datas.And so how to conduct effective data management and processing has become a key issue.This paper aims to study data product processing service system. Through the study of space weather,we make a standard format for the space weather data. And The system can provide a variety of data product processing services.Web Service is a revolutionary distributed computing technology innovation. We in-depth study the Web Service technology and apply the technology to data product processing service system, which effectively solve the information-sharing problem with the other system, we use CDF format as a standard space weather data format. CDF becomes the preferred space weather data format because of its self-descriptive nature, high-speed on reading the block data, and popularity in the space weather study .This paper first introduces the relevant background knowledge of the space whether data product processing.And then in-depth studies the Web Service technology and CDF format.After that it introduces the design of the data product processing service system.Finally,it uses a example of data product visualization to describe the implement process of the data processing service system.Data product processing service system is not only useful for space weather data center, but also has a very good reference for other science data center.
