| In this paper,in order to establish a fully functional,safe and stable,and meet the demand of land and resources management departments at the county level of permanent basic farmland management information system,emphatically has carried on the system database design and system function module.The establishment of permanent basic farmland management information system at county level provide a intuitive,efficient,fast work platform for land and resources management departments and land management workers,increase the strength of regulation and protection of permanent basic farmland,realize the informationization and intellectualization of basic farmland management.Object-oriented method has become the mainstream software development method.In the object oriented software development,the UML visualization modeling technology plays an increasingly important role.This article is based on UML unified modeling language(UML),using the core idea of use-case driven and iteration of RUP unified process,to analysis and design the county permanent basic farmland management information system.Establish the initial use case model by conducting research and interviews with the relevant departments of the land,obtaining the requirements of the system business,function and data.On the basis of analyzing the data requirements of the system,the data structure model is set up and the database of permanent basic farmland is designed.By using case refactoring,refining the system functionality,and combining use case description documents and UML activity diagrams to describe the functional modules of the system in detail;Using the C/S architecture,we rely on ArcGIS Engine quadratic development to achieve the design system.This article uses the UML visualization modeling language of object-oriented to model the software system,enhancing the flexibility,readability and intelligibility of the system design.At the same time,enriches the practice of RUP software development process. |
