Design And Implementation Of Unified Multiple Datasource Reporting Online Generation System

Document reports are widely used in a variety of scenarios.Parameterized report documents often have large amounts of content data,cross each other,and are logically complex.The generation process requires the report producer to open the data source files of different formats one by one,find the required data,and fill in manually.This method is labor intensive,inefficient,and error-prone.This paper designs and develops a unified report generation system,which realizes the separation of data and templates,and effectively manages templates and data source files.The main work is as follows: First,for the data source file,the mechanism of local and server synchronization is designed.The method of differential analysis is used to optimize the file uploading process and improve the file transfer efficiency.The second is to customize a set of template label syntax,provide an online template editing environment,version control of the template file,and implement a full-text search mechanism based on the word segmentation method.Thirdly,through the in-depth study of the document characteristics and the generation process,combined with the characteristics of the template and the data source file,the report generation engine is designed.The data set needed for the extraction can be loaded from the data source files of different formats,and the report can be generated efficiently and accurately.The fourth is to manage the generation process,solve the concurrency problem and the information exchange problem in the generation process.Through the testing of the system,the related problems are solved perfectly.A one-stop report generation system that is simple,stable and efficient.In the follow-up work,the types of supported data source files can be further expanded and closely linked with the production practice process to maximize the benefits...
