The Design And Implementation Of The Frontend Of Electronic Invoice Transcribing Platform System Based On Backbone

With the rapid development of Internet and the state vigorously promote the reform project to replace the business tax with a value-added tax, using electronic VAT invoices instead of regular paper invoice will be the new trend, and the electronic invoice will be comprehensively promoted. Users have to face these main problems, such as inconsistence of data and type between paper and electronic invoices, verification without traditional check method, docking between paper invoices and electronic invoice management platform and handle with enormous remaining non electronic invoices.For the problems above, this article focuses on the architecture and implementation of the frontend of the system which is used to interact with users and show the system’s functions. The frontend is built on Backbone architecture, helping validate and process invoices electronically.In this project, main works are as below:(1) introduce the current development of electronic invoice and its platform.(2) describe the architecture and technologies used in the frontend of the project, including MVC, Backbone, REST, Spring and other related technologies.(3) analyze the functional and nonfunctional requirements of the frontend, show the overall structure of frontend, the design of each module and the type-ahead recommendation.(4) mainly describe the implementation and process flow of each frontend module, main logic process and some sample tests.Each module of frontend has been implemented based on Backbone. The system is very convenient for customers to perform lots of validate operations with the help of type-ahead recommendation. The system’s frontend has been completed and put into production currently.
