Research Of GIS Business System Software Rapid Development Technology Based On Product Line Mode

GIS has been applied to every aspect of people’s production and life. Under thepolicy driven traction and application requirements, our GIS will have a morepromising market.GIS software as a kind of computer application systems, With a diversity ofapplications, the development of technical complexity and so on. The traditionaldevelopment model is still difficult to meet the needs of applications, such asfunctional reuse, business agility, flexibility to adjust visualization, etc.The main problems include:(1) GIS software development efficiency isrelatively low, business agility is not high;(2) a low level of software reuse;(3) GISsoftware development costs higher.The article is part of "Geospatial Information Processing Analysis Servicesdevelopment tools (Num:2011BAH06B00)", which is belong to National Science&Technology Support Project.The article focuses on GIS product line model, GISproduct line core asset development and maintenance, GIS production development.the main work is as follows:(1)The characteristic of GIS software development is studied, GIS product linesprocess model and GIS product line concept model are proposed. GIS product linecore assets be classified as architecture, standards resources, component resources,maps data visualization resources; GIS product development and maintenance toolsbe divided into framework interface design tools, resource directory design tools,permissions resource binding tools, etc.(2) Studied and proposed a conceptual model of GIS component library andresearched the realization mechanism of component library. Including componentmanagement forms, storage management, directory management, query and retrieval,reconstruction and polymerization, Multi-source heterogeneous component can beintegrated resource management and scheduling.(3) Study the principles and methods of workflow technology. According tointernational popular workflow reference model, designed GIS business logic control system, This system has a workflow engine, workflow designer, process definitiontools, and management and monitoring tools and other functions, it can achieve GISbusiness processes and systems to automate the process flow.(4) This paper studies the integration development environment of GIS businesssystems which based on software product line.The characteristics of the GIS businesssystem are been Researched, We achieved software visualization tools to build of GISbusiness systems, such as work space tools, interface design tools and rightsmanagement tools.(5) Based on software product line core assets and development maintenancetools, we designed build process and build steps of GIS business systems. Relying onsoftware product line, we developed a software landscaping of GIS business systems.Tests proved that the approach has a great advantage in development cost,development of technical difficulty, the development efficiency,which based onsoftware product line. For example, in the same task, the same person, the workingefficiency can be improved significantly.
