Continuous change of business environment of information system requires it timely respond and support these changes. A major challenge faced by information system is system reconfiguration, namely capability to quickly respond to changes of the system. Based on description of the concept of reconfigurable information systems, the idea of component was introduced into design and implementation of Reconfigurable Information System (RIS). Overall architecture and implementation method of reconfigurable information system based on component was analyzed in detail. Specific design of RIS based on component was provided combining with design and development of specific document transmitting system based on CORBA middleware platform.
