Study On Heterogeneous Data Integration Of Manufacturing Enterprises' The Management Information System

Management information system is an important interior resources for enterprises , it is also the main content of enterprise reconstruct, each enterprise has more requirements on system information. The manufacturing enterprises of our country have many independently management information systems due to technical and management reasons. There's no uniform technical and data standard among systems, which results in heterogeneous data, the data can't be automated transfer each other, information resource is separated and redundancy. Also it reduces the management efficiency, many business can be neither run smoothly, nor be controlled effectively. Heterogeneous data has already been austere topic nowadays.In this thesis, the background of the theme was introduced, the status of management information system in manufacturing enterprises of our country was described, the reasons of heterogeneous data was analyzed, then we studied from three parts:1. How to stop the produce of heterogeneous data? The concept of IT layout was introduced, the meaning of IT layout was described, then we sum up how to do IT layout.2. How to reduce the produce of heterogeneous data? This thesis focus on the daily job of IT department, standardize the business process, unionize data flat and integration standard were analyzed to reduce the produce of heterogeneous data.3. How to integrate the existing heterogeneous data? The meaning of heterogeneous data integration was analyzed, some common methods were introduced, include CORBA, data warehouse, XML.In order to provide the theories and technology support, an example of one manufacturing enterprise was applied for study. At the last part of the thesis is the conclusion and the future work.
