We have a long-term activities on the NMR spectral database system (SDBS-NMR) in a main-frame computer, which was finished at March 1999. The internet service of SDBS started from 1997 which achieved a great many accesses from the world. To continue the database activities, the database system on a PC was necessary, which was developed by using ISIS/BASE as an input tool. The chemical structures with spectral assignments are treated by molfiles. The spectral patterns displayed by a Java applet can be expanded easily. The DBMS is an ORACLE and since the present system has been developed on a web system in a PC, it is easily used as an intranet system.
