Along with the development of information society, universities are required not only to accumulate precious academic information but also to open them to the whole world. We are developing a general-purpose database system which manages and provides various kinds of information accumulated in our university. One of the most important points in the design of the system is management of the enormous amount of data, which comes up to several tera-bytes in the field of natural science in some cases. In the present study, we constructed a database system on the geospace radio environment obtained by the Akebono satellite. This is a model case of enormous database systems especially in natural science because there are huge and variety kinds of data on the space environment measurement. In order to improve the system performance, we synthetically examined the flow of functions from construction of the database, data retrieval, and data distribution through the computer networks. In the present paper, we introduce the system and evaluate its performance.
