A distributed, component-based solution for scientific information management
Jain, Lalit Kumar
Date:
1998-07-01
Abstract:
This paper describes the design and performance of a distributed, multi-tier architecture for scientific
information management and data exploration. A novel aspect of this framework is its integration of
Java IDL, the CORBA distributed object computing middleware with JavaBeans, the Java Component
model to provide a flexible, interactive framework for distributed, high-performance scientific data
visualization. CORBA server objects running in a distributed, collaborative environment provide data
acquisition and perform data-intensive computations. Clients as Java Bean components use these
server objects for data retrieval and provide an interactive environment for visualization. The server
objects use JDBC, the Java application programming interface to databases, to retrieve data from the
distributed data stores. We discuss the system framework and its components and describe an example
application and its performance.
