DBMS performance : Our system adopted small codebase DBMS and did not support SQL which will raise performance degradation in amount of data. The information sharing system called HIC currently in beta test is connected to each HANB-ISDN project via Internet. In addition, the ultimate target of this system is to realize operation on the B-ISDN National Test-bed, scheduled to be fully tested in Korea starting July. To realize this, the protocols currently used by WWW can be used without motifications by using the IP over ATM, or LAN Emulation, system or the new WWW protocols may be used on ATM LAN. Research with regard to this aspect is scheduled for the future. In addition, the current document management function, because it uses a small DBMS in which all documents are stored simply in the €0” of text files using existing systems, contains a considerable degree of restriction on data manipulation. However, if this system is heavily accessed, and considerable amounts of documents and opinions are exchanged, the commercial DBMS will be planned, to ensure more effective document management. In addition, research is scheduled to be carried out also on real-time web application, for effective operation of our system.
