Database centered simulation using WWW

ABSTRACT

A model for WWW based simulation environment is presented. The simulation environment is coordinated through a RDBMS that contain both spatial and time series data for use with forecast and simulation programs. Any client WWW browser can communicate with the Database either through the Web Server or directly through Java applets. The data preparation and execution as well as storage of the output in the database is automated through database scripts that are stored within the database. Communication with operating system resident simulation programs is carried out through server side Java programs initialized by the database trigger scripts. This approach provides a generic mechanism for integrating spatial and time series data with simulation programs to carry out scenario modeling and impact assessment studies. The methodology is scalable and can evolve into a decision support system incorporating database and simulation functionality
