The Internet Databases of the World Data Center for Geophysics, Beijing

Since the 1990s, our center's geophysics database has been available on the Internet (http://gp.wdc.cn and http://wdc.geophys.cn). Based on HTML language, the website offers simple data service and is being constantly upgraded and improved. We have adopted ORACLE as the database and use JSP (Java Server Pages) technology to create dynamic pages. The basic function of the network is to store, check, inquire, and renew the data. Users can query and download the data in txt form and view pictures generated by Matlab. At present the system is running well in both versions: Chinese and English, each having a unified style. The pages are simple and convenient to use. Its users come from most provinces of China, including Taiwan, and from developed or developing countries, such as the U.S.A., Germany, Japan, Singapore, Bulgaria, Canada, etc.
