Trajectory Databases: Data Models, Uncertainty and Complete Query Languages
Moving objects produce trajectories. We describe a data model for trajectories and trajectory samples and an efficient way of modeling uncertainty via beads for trajectory samples. We study transformations of the ambient space for which important physical properties of trajectories, such as speed, are invariant. We also determine which transformations preserve beads. We give conceptually easy f...
متن کاملData Models and Query Languages for Spatial Databases
The main purpose of this paper is to investigate the characteristics that distinguish spatial databases systems from traditional ones. Hereto, we give an overview of some well-known data models and query languages of spatial database systems. We also investigate the concept of genericity, as introduced by Chandra and Harel for classical databases [6], for spatial databases. Paredaens, Van den B...
متن کاملMining Databases and Data Streams with Query Languages and Rules
Among data-intensive applications that are beyond the reach of traditional Data Base Management Systems (DBMS), data mining stands out because of practical importance and the complexity of the research problems that must be solved before the vision of Inductive DBMS can become a reality. In this paper, we first discuss technical developments that have occurred since the very notion of Inductive...
متن کاملComplete Geometric Query Languages
We extend Chandra and Harel s seminal work on computable queries for re lational databases to a setting in which also spatial data may be present using a constraint based data model Concretely we introduce both coordinate based and point based query languages that are complete in the sense that they can express precisely all computable queries that are generic with respect to certain classes of...
متن کاملData Models and Query Languages for Linked Geospatial Data
The recent availability of geospatial information as linked open data has generated new interest in geospatial query processing and reasoning, a topic with a long tradition of research in the areas of databases and artificial intelligence. In this paper we survey recent advances in this important research topic, concentrating on issues of data modeling and querying.
