  • Patent number: 5887171
    Abstract: A document management system a high extendability, flexibility, and stability capable of solving a problem that, as an agent-oriented paradigm system extends, the number of agents increases and indefinite factors increase. In the system configuration with an object execution environment implemented with an object-oriented function and an agent execution environment implemented with an agent-oriented function, a unit for changing an agent into an object is provided for using the agent execution environment as the object execution environment. With this configuration, a system developer can use the merits of both the object- and agent-oriented paradigms by implementing a function necessary for stable operation by an object and a function with high change occurrence frequency by an agent.
