The expressive power of temporal relational query languages

A.U. Tansel, E. Tin
1997 IEEE Transactions on Knowledge and Data Engineering  
We follow a comparative approach in evaluating the expressive power of temporal query languages, using NTC as a metric and comparing it with the existing temporal query languages.  ...  For this model, a nested relational tuple calculus (NTC) is defined.  ...  ACKNOWLEDGMENTS The authors would like to thank the reviewers for their comments and Dr. Susan Urban, the subject editor, for meticulously handling the manuscript.  ...

Supporting temporal queries on clinical relational databases: the S-WATCH-QL language

C Combi, L Missora, F Pinciroli
1996 Proceedings : a conference of the American Medical Informatics Association. AMIA Fall Symposium  
In this paper we describe S-WATCH-QL (Structured Watch Query Language), a temporal extension of SQL, the widespread query language based on the relational model.  ...  Due to the ubiquitous and special nature of time, specially in clinical datábases there's the need of particular temporal data and operators.  ...  Stefano Fattore, for their help in focusing the clinical problem.  ...

STOQL: An ODMG-Based Spatio-Temporal Object Model and Query Language [chapter]

Bo Huang, Christophe Claramunt
2002 Advances in Spatial Data Handling  
Spatio-temporal databases are a topic of growing research interest but there is still little work reported on spatio-temporal query languages in line with the Object Database Management Group (ODMG) standard  ...  This language is based upon a data model that extends the ODMG Object Model with basic spatial and temporal types as well as a parameterised type, Temporal, which lifts spatial types into spatio-temporal  ...  Acknowledgements Part of the work in this paper was done when the first author was working for the joint TRIPOD project between Keele University and Manchester University, UK.  ...

Spatio-temporal database support for legacy applications

Michael Böhlen, Christian S. Jensen, Bjørn Skjellaug
1998 Proceedings of the 1998 ACM symposium on Applied Computing - SAC '98  
These requirements provide a foundation for making it economically feasible to migrate legacy applications to a spatio-temporal DBMS.  ...  In areas such as finance, marketing, and property and resource management, many database applications manage spatio-temporal data.  ...  The responsibility for any simplifications or distortions of that application is ours entirely.  ...

Paolo Terenziani, Richard T. Snodgrass, Alessio Bottrighi, Mauro Torchio, Gianpaolo Molino
2005 Lecture Notes in Computer Science  
In the area of Medical Informatics, there is an increasing realization that temporal information plays a crucial role, so that suitable database models and query languages are needed to store and support  ...  We propose a new three-sorted model and a query language that overcome such limitations.  ...  For instance, in many approaches, such as SQL/Temporal, TSQL2, TSQL, HQL, and TQuel, and Gadia's [8] Homogeneous Relational Model, a temporal element (a set of time intervals) is associated with each  ...
