Abstract
The organization and functions of the new academic information system are explained by the use of the illustrated model comprising of four phases. A large sized computer center which is shared for the nationwide use is located at the center of the model. Through the trend of the wishes which the users of the large sized computer center have presented it is predicted it is predicted that centralized & specialized centers responding to the each phase or the decentralized systems will become independent from the computer center progressively. In the new comprehensive academic information system the computer center plays one of the key roles, that is, the role to link the components which are heterogeneous each other both in the centralized systems and decentralized systems. Geo-Database System GEODAS is considered to be the typical example of the information activities formulated in the model.
