The expressive power of temporal relational query languages
1997
IEEE Transactions on Knowledge and Data Engineering
Preserved Fulltext
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. ...
