Time and Relational Theory

Temporal Databases in the Relational Model and SQL

C. J. Date, Nikos Lorentzos and Hugh Darwen

2nd ed. Morgan Kaufmann, 2014.

ISBNs 9780128006313

Colección: ScienceDirect

Resumen (en inglés):

Time and Relational Theory provides an in-depth description of temporal database systems, which provide special facilities for storing, querying, and updating historical and future data. Traditionally, database management systems provide little or no special support for temporal data at all. This situation is changing because:

Cheap storage enables retention of large volumes of historical data in data warehouses
Users are now faced with temporal data problems, and need solutions
Temporal features have recently been incorporated into the SQL standard, and vendors have begun to add temporal support to their DBMS products

Based on the groundbreaking text Temporal Data & the Relational Model (Morgan Kaufmann, 2002) and new research led by the authors, Time and Relational Theory is the only book to offer a complete overview of the functionality of a temporal DBMS. Expert authors Nikos Lorentzos, Hugh Darwen, and Chris Date describe an approach to temporal database management that is firmly rooted in classical relational theory and will stand the test of time.

This book covers the SQL:2011 temporal extensions in depth and identifies and discusses the temporal functionality still missing from SQL.

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
Appreciate the benefits of a truly relational approach to the problem with this clear, user friendly presentation

Time Frequency Analysis

A Comprehensive Reference

Boualem Boashash

Elsevier Science, 2003.

ISBNs 9780080443355

Colección: ScienceDirect

Resumen (en inglés): Time Frequency Signal Analysis and Processing covers fundamental concepts, principles and techniques, treatment of specialised and advanced topics, methods and applications, including results of recent research.

This book deals with the modern methodologies, key techniques and concepts that form the core of new technologies used in IT, multimedia, telecommunications as well as most fields of engineering, science and technology. It focuses on advanced techniques and methods that allow a refined extraction and processing of information, allowing efficient and effective decision making that would not be possible with classical techniques. The Author, fellow of IEEE for Pioneering contributions to time-frequency analysis and signal processing education, is an expert in the field, having written over 300 papers on the subject over a period pf 25 years.

This is a REAL book, not a mere collection of specialised papers, making it essential reading for researchers and practitioners in the field of signal processing.

*The most comprehensive text and reference book published on the subject, all the most up to date research on this subject in one place
*Key computer procedures and code are provided to assist the reader with practical implementations and applications
*This book brings together the main knowledge of time-frequency signal analysis and processing, (TFSAP), from theory and applications, in a user-friendly reference suitable for both experts and beginners
