In this paper, we defined the concept of the grouped distributed objects, as a logical unit of distributed application service, and developed a distributed programming developing tool-kit based on object group model (OGM-DPD Tool-Kit). This tool-kit can provide not only dynamic binding strategy among distributed objects and distributed services using the distributed object group framework (DOGF) we constructed before, but also implementation of distributed applications easily. Based on the DOGF, this OGM-DPD tool-kit provides the functionalities of the register/withdraw management, the access security management for individual distributed object, and the object name/property management as group units in the point of view of distributed object management. In the point of view of distributed service, our tool-kit includes the DOGF that can support naming service, dynamic binding service, replication service, and load balance service for distributed application services. In this paper, we in details specified the object group model and the architecture of the DOGF supporting this tool-kit. finally, we implemented a simple distributed application using this tool-kit, and showed the execution of this application to verify the executabilities of the distributed object group management and the distributed services described above.
