| With the popularity and development of the Internet,various levels of government and institutions in China have launched various online government service to improve business efficiency.Today,with the globalization of the world,barcode technology has been applied to the coding of goods,making barcode become an "identity" in the international market.China currently lacks a system dedicated to handling commodity bar code services,The purpose of this paper is to design a set of product bar code business management systems that are compatible with the internationally-available GS1 coding system based on the actual needs of the China Article Numbering Center,in order to provide online self-service for enterprises to handle commodity bar code services.The implementation of this system will greatly increase the efficiency of business users in handling commodity bar code-related businesses,reduce the intensity of the work of encoding agencies,and further promote the development of China's commodity bar code business.This paper fully investigates the actual situation of business users to handle commodity bar code business.Through the analysis of the needs of enterprise users and commodity coders and the analysis of system business processes,the system's architecture and business processes are carefully planned and designed.The main work and innovations of this paper include the following aspects:(1)Investigating the business process of bar code processing.Study the process of online registration of the China Article Numbering Center website.Combine the opinions and suggestions of the local coding organization and coding center for business management.Analyze the functional and non-functional requirements of the system.(2)Designing the overall system plan and modularizing the system and detailed design of the system.Through the analysis of the business process,the entity classes are abstracted,and the database table structure and table fields are rationally designed and the data dictionary and data flow are designed.(3)For sensitive data security issues,The system uses MD5 algorithm and Base64 encoding mixed encryption.During the remote call,MD5 encryption is performed on the XML formatted password transmitted over HTTP.For file uploads and image storage issues,Invoking Web Service interface to compress JPEG files ofdifferent types of files under the same service and synthesize a multi-image TIFF file for unified storage.For the problem of file identification and search difficulty,Code128 algorithm was used to generate barcode images to mark SN.(4)Develop system modules and functions based on system design and key problem solutions.The system realizes registration of system members,change of information,increase of bar codes,renewal,change and renewal,and registration of subsidiary company.Research and implement encryption algorithms,one-dimensional barcode generation algorithms,multi-image TIFF file synthesis technologies,and SMS notification services.Completed the integration debugging work of the system and the national code center auditing system.The system has been used on the National Coding Center and has been operating stably.(5)Provide users with WeChat applet to query barcode business information service.Design and implement the function of WeChat applet querying business progress,which can provide a faster user experience than browser.The user can log in to the product bar code system from the applet to facilitate the user to obtain the business management information in time. |
