Industry Process Monitoring System Based On Three-Tier Model Architecture--The Design And Implementation Of Middle Tier

This paper introduces our research background, our system requirements, as well as the background of the leading technologies adopted in the research. We also make a detailed explanation on the analysis of the enterprise's application environment, the middle-tier's interfaces design and the implementation methods using on the objects interfaces. Meanwhile, we have successfully applied the component architecture and the object interfaces to an actual project, which has been checked and accepted by the company. This system did make remarkable benefits for the company.We have done some researches and implementation work on the service tier (middle-business logic tier). It functions as a link between the database tier and the client tier (including data-collecting and data-viewing). Moreover, it reduces the resources expenditure, lowers the database server's burden, secures the systems stability. We do reach our research goal as expected.
