Key Technologies of Heterogeneous System General Data Service based on Virtual Table

Abstract

In order to meet the increasing demand of cross business information interaction and reduce the difficulty of information interaction between different message buses and service framework products, this paper proposes a general service access method for information resources between heterogeneous systems of power grid regulation and control, which abstractly maps the service access call to table data query in the form of virtual table, and carries out the service query through virtual database service agent for reducing the cost of information sharing between heterogeneous systems, the unified access interface is adopted to simplify the process of information acquisition in wide area heterogeneous systems. At the same time, the experimental verification environment is built to test the cross system data access performance after the transformation.
