The Research And Design Of Piece Rate System At Port Group Based On Knowledge Base

With the development of computer technology, the enterpriseinformationization is one of valid meansure which make enterprise successful in thecompetition. As for the port group, the Management Information System not only canprovide the information and data in time and completely, predigest managementdepartment member and the worker's work, put forward a different report to thedifferent management layer, but also predict a future circumstance according to the pastdata.This article through analysis the requirement of Piece Rate System at Guangzhou PortGroup, we bring forward the theories of the Knowledge Base to design the Piece RateRule Base which take Object-Oriented Knowledge Representation as core, takeRelational Database as finally storage material at J2EE Framework in the wholeManagement Information System. And O/R Mapping Tool is a scheme of datepersistence used to solve the "impedence mismatch" between the relational model andthe object model. We build an efficient, safe, loose, coupling and high integration PieceRate System at Port Group which is used to calculate Piece Rate automatically. In thispaper I make some research on the nuclear technologies (UML modeling technology,Hibernate technology based on object/relational mapping and other J2EE LightweightFramework technology).This paper falls into 6 chapters, introducing the research background, significance first.Then some researches of knowledge and Knowledge Base technique foundation isintroduced.Then introduces the function requirement of Piece Rate System and ManagementInformation System at Guangzhou Port Group, and introduces some J2EE Frameworktechnology.And then mainly introduces the concrete design way of Knowledge Base, and Hibernatetechnology based on object/relational mapping.Introduces the concrete design of the Piece Rate system finally, and put forward theproject of the system testing theory.
