Remote method invocation based Web database system for global environment models

The remote method invocation (RMI) based Web database system is implemented for global environment models allocated on many servers on the Internet. These distributed environment models are regarded as the Web database which is invoked remotely. We present a client-server architecture of the Web database from the viewpoint of object oriented programming. The global environment model is expressed by an autoregressive equation whose input and output are environment indices. We also present a graph theory based depth first search to obtain the model path which is a sequence of environment models from initial input to final output. The designed user interface of the Web database system is also shown.
