Design And Implementation Of Web-based Project Management Information System

If a company has an efficient, suitable project management system, can easilymanage the projects. Through management system to collect the information from theprocess, maintain project software, codes and documents, clearly know the informationin the development, this is important for estimating the cost, optimize the process,document management, project quality control and decision.This thesis through analyze business of a researching organization, understands therequirement of the project management system, using the object-oriented thinking todescribe the system requirements analysis and design. In the requirements analysisphase, through the interface of the use cases, requirements specifications, businessprocesses and other means to show the system to be elaborated to achieve the mainfunction; In the system design phase, given the system ’s design goals and principles,describing the basic settings, project management, schedule management, detaileddesign of major system modules, use the database model structure, relational tablesand other tools introduced the system database design case; In the systemimplementation phase, introduced the system hardware and software developmentenvironment and environment configuration, describes the system implementationfunction, and shows some features of the system implementation code. To this end, thesystem development process to solve the main problems is, based on the demand of aresearch unit clerk project management information system needs analysis andplanning, design and optimization of database objects, object-oriented technology,AJAX technology and Extjs Framework in the project development process andoptimize applications, and integration of CMMI-based software process managementthinking in the system design and implementation of the process save the document,process metrics analysis of some features will help enterprises through the system toachieve its continuous improvement.The experimental results of the system showed that the system operate correctly,and basically complete the features, implemente the interface with other informationsystems, achieve the designed goals and requirements, can provided a better projectinformation management services.
