| Abstract(in English) | In recent years, plant monitoring and control systems are constructed utilizing not only traditional controllers but also general purpose computers such as workstations and PCs. This paper proposes an object model to realize database management systems for plant monitoring applications in such an environment. Three types of temporal objects are provided to represent continuously-changing data in a plant and temporal validity is defined for each type of temporal objects to manage the consistency between an actual plant status and values in the temporal objects. The paper also illustrates an application example of the database system based on the proposed object model. |
