Research On Data Export Model For Web System

With the rapid development of network technology,Web applications are widely used,changing the way people live and work.Large amounts of data stored in Web need to be exported,displayed,or even migrated to other systems.In view of the problem that the data conversion tool on the line can't combine with the Web system,it is necessary to study the data export model for the Web system,which not only satisfies the data of transformation of ordinary users,but also satisfies developers' application in Web project development.Firstly,the logical model of data export on Web system was described in detail,and the intermediate data was introduced.The model hierarchy of the source data layer,the intermediate data layer,the target data layer and the management layer was built.In the model,the data form and data structure were combined to design the source data type definition framework.The source data type and target data type supported by the model are given,and the intermediate data form of the model was defined,and the definition framework of conversion rules between data item types was designed.Secondly,the implementation framework of the data export model on Web system was built,and some common data storage modes on Web was analyzed.Based on the intermediate data form defined by the model,the Microsoft SQL Server database was used as the storage way of the intermediate data.The method of source data type analysis and the data conversion were realized by using NPOI library and Aspose components that combined with the strategy mode coding.In addition,the conversion rules were called in the transformation method to realize data content conversion.Finally,this paper designed the experimental scheme,and applicated the model in several actual enterprise projects.In particular,The source data form and structure analysis of the application example were implemented.By transforming the rules to generate the actual intermediate data that conforms to the definition of intermediate data,the requirements of the target data were analyzed and the results were derived.With the implementation of different export requirements in different Web applications,this paper analyzed the application process and results,and the practicality of data export model forWeb system was illustrated.
