Design And Implementation Of Data Middleware In The Real Time Information System

With the rapid development of industry, the management is more and more scientific. And many managers must know the data on the spot in order to manage and make decision-making. So The Real Time Information System in the locale of industry should been built, and the real time data was past to manager by the computer network. And managers can also obtain the real data and historical record by interface producted by this system.The Axletree Test System is actualized as an example in this paper, And the work content in every phases of The Real Time Information System is discussed. On the base of analyse the characteristic of all kinds of real time information data resource on the spot, This paper gives the project of real time data's transmission, display, organization,, management and storage, and also introduces the data middleware's design and actualization.System implements Middleware technology, and provides net information service, parallel access service and data consistency service, Database connection pool service. So Data middleware covers up the differences among all kinds of real time data, and provides consistent interface of data access. Data access interface is designed based on J2EE platform in order to enhance system's current.
