Querying the uncertain position of moving objects

A Prasad Sistla, O Wolfson, S Chamberlain… - … databases: research and …, 1998 - Springer
In this paper we propose a data model for representing moving objects with uncertain
positions in database systems. It is called the Moving Objects Spatio-Temporal (MOST) data …

Semantics of time-varying information

CS Jensen, RT Snodgrass - Information Systems, 1996 - Elsevier
This paper provides a systematic and comprehensive study of the underlying semantics of
temporal databases, summarizing the results of an intensive collaboration between the two …

Moving objects databases: Issues and solutions

O Wolfson, B Xu, S Chamberlain… - … Conference on Scientific …, 1998 - ieeexplore.ieee.org
Consider a database that represents information about moving objects and their location.
For example, for a database representing the location of taxi-cabs a typical query may be …

Temporal and real-time databases: A survey

G Ozsoyoglu, RT Snodgrass - IEEE Transactions on …, 1995 - ieeexplore.ieee.org
A temporal database contains time-varying data. In a real-time database transactions have
deadlines or timing constraints. In this paper we review the substantial research in these two …

Temporal databases

RT Snodgrass - Theories and Methods of Spatio-Temporal Reasoning …, 2005 - Springer
This paper summarizes the major concepts, approaches, and implementation strategies that
have been generated over the last fifteen years of research into data base management …

On the semantics of “now” in databases

J Clifford, C Dyreson, T Isakowitz, CS Jensen… - ACM Transactions on …, 1997 - dl.acm.org
Although “now” is expressed in SQL and CURRENT_TIMESTAMP within queries, this value
cannot be stored in the database. How ever, this notion of an ever-increasing current-time …

Logical approaches to incomplete information: A survey

R van der Meyden - Logics for databases and information systems, 1998 - Springer
The observation that it is frequently impossible to obtain complete information in the context
of database applications has motivated a substantial literature seeking to extend the …

Supporting valid-time indeterminacy

CE Dyreson, RT Snodgrass - ACM Transactions on Database Systems …, 1998 - dl.acm.org
In valid-time indeterminacy it is known that an event stored in a database did in fact occur,
but it is not known exactly when. In this paper we extend the SQL data model and query …

Transfer re-identification: From person to set-based verification

WS Zheng, S Gong, T Xiang - 2012 IEEE Conference on …, 2012 - ieeexplore.ieee.org
Solving the person re-identification problem has become important for understanding
people's behaviours in a multicamera network of non-overlapping views. In this work, we …

Probabilistic temporal databases, I: algebra

A Dekhtyar, R Ross, VS Subrahmanian - ACM Transactions on …, 2001 - dl.acm.org
Dyreson and Snodgrass have drawn attention to the fact that, in many temporal database
applications, there is often uncertainty about the start time of events, the end time of events …
