Taschenbuch. Condizione: Neu. Neuware -Moving objects database has been active in the database community during the last 20 years. The task is to manage spatial objects continuously changing their locations over time. Users send their queries to know when and where of objects and will benefit from historical trips. Besides location and time, transportation modes such as BUS and WALK illustrate the geographical environment and describe in detail how objects move in available spaces. Such pieces of information represent preferences and habits for travelers, but do not receive adequate attention in the literature. Moving objects databases should enhance the capability to handle not only spatial objects continuously changing locations over time but also transportation modes in order to provide comprehensive knowledge about real-world objects. This book makes a complete and systematic introduction about moving objects with transportation modes, including data model, data generator, 3D visualizing moving objects, searching visible points in obstacle space, trip planning in diverse environments, indexing and querying moving objects with transportation modes, and a benchmark for moving objects with transportation modes.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 208 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The new applications on detecting transportation modes and advanced trip recommendations make it crucial to investigate moving objects with different transportation modes. The aim of the book is to (1) define a datamodel that represents moving objects with different transportation modes in a database system; (2) provide efficient query processing mechanisms enabling to support novel queries; (3) evaluate the performance of such a database system called GMOD (Generic Moving Objects Database) that manages complete trips for humans. Towards this goal, at first we propose a generic method that is able to represent the location of a moving object in all environments. Since each environment consists of a set of geographic objects, a group of data types is designed to represent them. A data type for generic moving objects is defined where the location is represented by referencing to geographic objects. Afterwards, a set of operators is proposed to efficiently access the data. Definitions of both syntax and semantics are given. The proposed operators are also used to formulate queries. The data model is implemented in a database system.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 144 pp. Englisch.
