In current information age,how to retrieve,use and manage the huge amount of information is an important issue. In addressing this issue we propose the concept of information object to construct an information system. An information object is the basic unit in the information management system. An information object is an entity that encapsulates the required data and methods in a unit. The methods of an information object can be flexibly installed or changed as needed. In thesis, we apply the information object concept to develop a member oriented information system. In our development, a member object is built for representing a member in an institute. All the member objects in our system can be easily composed to become an object representing the institute. We will describe the basic concept of the information object and the design of the prototype system developed on the Web platform.
