Temporal data and the relational model : a detailed investigation into the application of interval and relation theory to the problem of temporal database management by C. J Date( Book )

21 editions published between 2002 and 2003 in English and Undetermined and held by 196 WorldCat member libraries worldwide

P Temporal database systems are systems that provide special support for storing, querying, and updating historical and/or future data. Current DBMSs provide essentially no temporal features at all, but this situation is likely to change soon for a variety of reasons; in fact, temporal databases are virtually certain to become important sooner rather than later, in the commercial world as well as in academia. This book provides an in-depth description of the foundations and principles on which those temporal DBMSs will be built. These foundations and principles are firmly rooted in the relational model of data; thus, they represent an evolutionary step, not a revolutionary one, and they will stand the test of time. This book is arranged in three parts and a set of appendixes: * Preliminaries: Provides a detailed review of the relational model, and an overview of the Tutorial D language. * Laying the Foundations: Explains basic temporal data problems and introduces fundamental constructs and operators for addressing those problems. * Building on the Foundations: Applies the material of the previous part to issues of temporal database design, temporal constraints, temporal query and update, and much more. * Appendixes: Include annotated references and bibliography, implementation considerations, and other topics. Key features: * Describes a truly relational approach to the temporal data problem. * Addresses implementation as well as model issues. * Covers recent research on new database design techniques, a new normal form, new relational operators, new update operators, a new approach to the problem of "granularity," support for "cyclic point types," and other matters. * Includes review questions and exercises in every chapter. * Suitable for both reference and tutorial purposes
Spatio-temporal databases : the CHOROCHRONOS approach by Timos Sellis( )

1 edition published in 2003 in English and held by 29 WorldCat member libraries worldwide

This book summarizes in a timely and representative manner research carried out in the CHOROCHRONOS Project, established as an EC funded Training and Mobility Research Network with the objective of studying the design, implementation, and application of spatio-temporal database management systems. The nine coherent chapters by leading research groups are written in a tutorial style, making the research contributions of the project accessible to a wider audience interested in spatio-temporal information processing. Follwing an introductory overview, the book presents chapters on ontologies for spatio-temporal databases, conceptual models, spatio-temporal models and languages, access methods and query processing, architectures and implementation of spatiotemporal DBMS, interactive spatio-temporal documents, and future perspectives
Time and relational theory : temporal databases in the relational model and SQL by C. J Date( Book )

13 editions published in 2014 in English and Italian and held by 28 WorldCat member libraries worldwide

Based on new research led by the authors, this book offers a complete overview of the functionality of a temporal DBMS that describes an approach to temporal database management that is firmly rooted in classical relational theory and will stand the test of time. It covers the SQL:2011 temporal extensions in depth and identifies and discusses the temporal functionality still missing from SQL. You will understand how the relational model provides an ideal basis for taming the complexities of temporal databases; learn how to analyze and evaluate commercial temporal products with this timely and important information; be able to use sound principles in designing and using temporal databases; understand the temporal support recently added to SQL with coverage of the new SQL features in this unique, accurate, and authoritative reference; and appreciate the benefits of a truly relational approach to the problem with this clear, user friendly presentation. --
