The Design And Implementation Of A Distributed Database Project Management System For Communications Engineering Design

The enterprise information is one of the factor that carrying out the enterprisecan keep on a development, is also the foundation that the enterprise raises acompetition ability, the enterprise information construction already drive more andmore of the enterprise value. The ZhongRui communication planning and DesignCompany has been already developing the system of project management since thenend of2012,in order to improve the level of project management, to improve thelevel of information technology application, to improve the competitiveness ofZhongRui Company. The subject, which is based on the developing of the projectmanagement system, analysis of background of project management and theZhongRui Company’s current status of information construction, completes thesystem’s requirements analysis, architecture design, distributed database structuredesign, program development, etc.Through the research on distributed database technology and combination withthe characteristics of ZhongRui Company headquarters and the branches dealingwith local communication engineering design business, the subject proposes adistributed database design based on a snapshot of the level of fragmentation, hybriddistributed database distribution strategy, and based on a scheme of asynchronousreplication and trigger. By the application of distributed database technology in thedeveloping of project management system, the system will change the traditionalcentralized data storage and allow various sites controlling their own data localize,and the system can update data by replication and trigger, to ensure datasynchronization, which will make the system more suitable for the geographicaldistribution of the company, such as ZhongRui Company, and which will reduce thesystem depending on the network environment.With the completing of the Communication Design Project ManagementSystem based on the distributed database, the integration of design projectmanagement can be achieved in the company headquarters and all branches, andwhich can improve project management and control performance, strengthen theprogress control and cost control of project, enhance the project’s overall profit level,promote the market competitiveness of the company’s promotion.Also, the developing project management system base on distributed databasecan provide a reference to information construction of communication engineeringdesign enterprises, especially the communication engineering design enterprises within the group.
