Research And Design In Integrating Office Document And MIS By Using Smart Client Technology

MIS has played obviously important roles in the informationization in enterprises. C/S and B/S are two traditional architecture for develope MIS, they have each advantages and deficiencies. MIS based on both architecture can manage structured data well, but there are large numbers of unstructured data dissociated from MIS. In most enterprises, unstructured data exist in Office document: Word and Excel. And in many departments, the number of unstructured data has increased annually at a rate as high as 200 percent. Faced with "explosive" increase of Office documents, MIS can not interact well all along. Although some people have been committed to find a scheme to integrate both two. Due to various technical constraints, the effect has not been very satisfactory.On the basis of analyses on the obstacles in the integration of Office documents and MIS by using previous technology, and in-depth studies on smart client and Web services technology, we adopted service-oriented smart client technology and proposed a creative scheme to integrate Office documents with MIS programs. And some relevant strategies were proposed to resolve difficult problems which may be encountered, including asynchronous communication, using a service-oriented approach to solve the off-line processing, followed by the data cache, data synchronization, conflict resolution and security, and other problem. For the interactive way of data migration form document to MIS, we changed the traditional "push" model to the "pull" model, so the server-side gain initiative in security. Also on the basis of analyses on the Office object model,we designed a ServerDocument class to achieve core functions of Office Smart Client. This resolution scheme combined functions of Offcie software, .NET Framewok and Web services, solved the interaction problems of two "isolated island" (documents and data). It can enhance the efficiency and accuracy for collecting data from documents, so that a large number of unstructured data dissociated from the MIS can be effectively dealt with. At the same time, documents have been made to have capabilities for off-line business processing, improving efficiency and receipts greatly.
