Geographic information systems (GISs) are becoming more widely used in transportation planning agencies, especially among metropolitan transportation organizations. The extension of GIS into transportation (GIS-T) is driven largely by the requirements of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA), the Clean Air Act Amendments of 1990, and legislation by states that mandate the development of transportation programs to reduce traffic impacts. Traditionally, transportation modeling of traffic impacts, calculation of vehicle emissions, and consideration of wider transportation planning effects, including transit, have employed different modeling techniques, often in different agencies or in separate sections within an agency. The results from these modeling and planning exercises have more often than not been displayed on different map bases, using different graphic programs to represent the data. The requirements of federal and state programs are encouraging modelers and planners to consider more consistent methods of data integration and display, hence the growing interest in GIS-T. The role of GIS-T in regional transportation planning is evaluated, including data integration issues, the configuration of transportation networks for use with GIS, and the linkage of transportation models to GIS.

This paper researches Shanghai’s real property registration, studying the data integration of the information database of real property unified registration in Shanghai and the establishment of information systems of real property unified registration. The means of data cleaning and data integration are used to consolidate all kinds of basic data for real property which are in complex structure and different formats, building a basic information database for real property and providing a strong support for the establishment of information platform.

AbstractDuring the last decade, several projects aiming at integrated clinical workstations have been described and several prototypes have been demonstrated. In most of these projects, the clinical workstation accesses information and functionality provided by the present proprietary legacy systems of health-care institutions. We discuss trends in integrated clinical workstations from the viewpoints of software engineering and integration, considering that the clinical workstation itself basically consists of three layers: a presentation layer, a data integration layer, and a communication layer. The software engineering view on clinical workstations focuses on the development of basic building blocks from which clinical workstations, specific to a particular medical domain, can be composed. The integration view on clinical workstations addresses methods and techniques to deal with the, in general, intrinsically closed information systems in health-care institutions.

Translation Scheme

This chapter presents a methodology and tools framework, called X-TIME, to support data integration via web sites. It is a data model translator toolkit based on a metamodel and XML technology that is aimed at facilitating the design of wrappers, semantic reconciliators or mediators. X-TIME is an adaptable semantics-oriented metamodel approach that takes into account important characteristics of interoperable information systems, including extensibility and composability. Extensibility requires a translation scheme that can easily integrate new data models while composability, which is the ability of an application to define dynamically the subset of data sources it needs, requires on-demand translation among a subset of data models. To meet these requirements, X-TIME is based on an extensible metamodel that defines a set of metatypes for representing meta-level semantic descriptors of data models that can be found in web sites. The metatypes are organized in a generalization hierarchy to capture semantic similarities between modeling concepts and correlate constituent data models of interoperable systems.

Manufacturing Data

During complex manufacturing process, various manufacturing information systems and management information systems are often existing as heterogeneous systems, and manufacturing data is distributed everywhere across the whole value chain of the enterprises. One of the most valuable targets in the integration of these manufacturing information systems is the sharing of enterprise resources which are described in different formats in different information systems. In this paper, meta-resource model is extended using workflow to combine enterprise resources together with business process during manufacturing. Then, an effective method of data integration is proposed based on the meta-resource model. In the proposed method, heterogeneous data is encapsulated in unified format of resource and binding with workflow so that data resources could be accessed according to the business process of manufacturing. Finally, case study shows that the resource-based data integration approach is more robot and flexible than traditional data integration method, especial under the environment of complex manufacturing.
