In order to integrate the current different application systems and databases and enhance the construction of data storage and sharing capability, considering the requirements of integrating the existing data resources and establishing the uniform information platform, the basic skeleton of the J2EEbased meteorological information system is devised, using the JDBC (Java Database Connectivity) technology to manage the consolidated operation among the heteromerous and dispersive databases. The application of the J2EE technology to the construction of the distributed and dynamic meteorological information system is discussed.
