Design and Implementation of a Project Management System Based on Product Data Management on the Baidu Cloud Computing Platform

摘要

Aiming at enterprises without commercial project management systems(PMS)in a product data management(PDM)environment,and using a cloud computing platform,this research analyses the business process and function of complex product project management in PDM,and proposes a PMS-based organizational structure for such a project.This model consists of a task view,user view,role view,and product view.In addition,it designs the function structure,E-R model and logical model of a PMS database,and also presents an architecture based on the Baidu cloud platform,describes the functions of the Baidu App Engine(BAE),establishes the overall PMS software architecture.Finally,it realizes a revised product design project by using EasyUI,J2EE and other related technologies.Practice shows that the PMS designed for PDM has availability,scalability,reliability and security with the help of the Baidu cloud computing platform.It can provide a reference for small-and medium-sized enterprises seeking to implement information systems with high efficiency and at low cost in the age of big data.
