Design And Implementation Of Sanming City Road Engineering Project Management System

At present,with the development of traffic construction in China,the market of engineering project management software has been relatively mature,but in scalability,tailorability,openness,and professional application have broad market prospects for development.Especially because most of the existing engineering project management system without using the current epidemic information technology and advanced management concept,so the whole scheme is limited to the past technology,development space is not large,and the lack of vitality.At the same time,with the constant development of the business to change previous information on the objective conditions of non-isolating informatization construction,build a unified system is responsible for government departments(highway),enterprises and the public,and many other transaction support.In this system,the road engineering management is a very important function,not only involves the personnel is more,but also directly reflect the daily business process of road administration.Road engineering management part of the system structure is complex,adopted technology.In this thesis,the main contents are the following several aspects:1.In the requirements analysis phase,research road engineering project management system first general introduction to the system demand,the introduction of a use case diagram for thinning demand,secondly,using the entity relationship diagram,data flow diagrams and other related to demand analysis,finally summarizes the demand of road engineering project management system.2.In view of the road engineering project management system in the interaction between modules,frequent business coordination and data exchange.So the road engineering project management system introduced SOA framework,combined with the ESB bus technology,through a service reuse of simplifying the system integration development process,improve the efficiency of the software integrated development;Services through weaved improving responsiveness to business change,realize the unity of the interface and flexible configuration.3.Because the road engineering project management system to the level of data access requirements,in order to solve the access to the data type flexible adjustment problems,design the data level permissions management service,the service is mainly using rule engine way to promote reasoning the body's ability to access data,realize the system access control.4.Part of the business in the road engineering project management system involves the concept of workflow,in combination with the practical situation of the project requirements in this thesis,design a lightweight workflow engine,the engine covers the relevant type and necessary operation in the process of workflow execution.In this study,implement the change approval process Settings,access control,business flow,etc.5.Finally,the test system adopts the method and strategy studied.To software engineering life cycle process as the guidance,from the unit test,integration test,system test of road engineering project management systems were tested,and final testing results has given.Test results for the system in the development of each link,achieved the anticipated goal.The road engineering project management system has been put into use,the feedback from users and system running situation once again proves the applicability and stability of the system.
