Analysis And Design Of Rural Highway Management Information System

With the development of IT technology, all over the world are trying to apply it in daily life.Rural road is the main part of road, and it is faced an new challenge in the21th century. We base on the need of rural road management work.This thesis firstly introduces the research background of Rural road management system, and overviews the problems that we should solve. We discuss the significance and importance of the project, describe the system development methods and related technologies.This paper also presents the system design goals, carries out a detailed demand analysis, including business requirements analysis, functional requirements analysis, data requirements analysis and non-functional requirements analysis, Besides,we give the Transaction Flow Diagram(TFD), data flow diagram, Functional data analysis diagram (IPO chart), and describe data dictionary. We make the overall design of the system and module design, give the total system function block diagram (H chart), including project report funds management、project schedule modules and other functional modules,and each module is designed to give a specific functional block diagram (H diagram), IPO table, and process flow diagram. We clearly describe design and use ER diagrams and entity-relationship database table structure to design database in detail. Finally, We summarize the contents of the research,and explain the main work. We also point out the disadvantages of this paper, and further work we must do.
