Development System Chain of Business-Oriented Spatial Information Service
///This paper presents a development system chain to build integration environment providing resource integration management, function modeling, and application system building. General model for developing, deploying, and extending business-oriented spatial information service is introduced. Based on a flexible architecture termed suspended inversion model, the chain introduces the conception of development model and function warehouse, defines the hierarchical relation of service development and user group, integrates a set of norms including service development and resources management, a set of tools including service development and maintenance, and deployment model, and finally maximizes its applications.
