Design And Implementation Of Jingjiu Purchase Management System Based On MongoDB

The rapid development of information and network technology has stimulated the development and reform of various industries such as the manufacturing industry,and many systems for managing procurement have emerged.However,these systems are generally similar in function and cannot be specifically analyzed for specific problems,and their utilization efficiency is low.This leads to inefficient management,and this situation is very detrimental to the company's future growth and progress.For a company in Shandong,a large number of documents,pictures,and quality inspections will result in recordings,videos,etc.during the procurement process.The data volume is huge and the data types are various.If the system still uses a traditional relational database,then many features will be limited.Therefore,in this context,this paper focuses on the data storage problems in the procurement system where the data types are various and the data volume is huge,and a more electronic procurement for the company's own needs is realized from the aspects of procurement,finance,suppliers,and basic data.Management system.The main work of this article includes:First,the needs of the system data storage and system procurement management,financial management,supplier management and basic data management needs analysis.Second,according to the characteristics of system data,the system data storage structure,the overall architecture of the system,logical architecture and functional architecture are outlined.Third,detailed design of each functional module,unstructured data storage,database,and service interface of the system is described in detail through process introduction,sequence diagrams,and key code display.Finally,a screenshot of the system is given and tested.Completed system.The framework of the MongoDB-based fine procurement management system is the current popular full-JavaScript end-to-end web development framework,ie,the MEAN architecture.The front and back ends are written in JavaScript and use the B/S architecture.The database is set-oriented.The non-relational database MongoDB can store data of different data types in the same collection,and has the advantages of good scalability,easy management,and quick access.The database is currently the most popular and has the best support.NoSQL database,complete data processing of a large number of data structures in the system.At present,the system is being trialed by a company in Shandong,and has achieved certain results.It has improved the efficiency of collaborative work among the staff of the procurement department and the management of management.
