Synopsis
Excerpt from Virtual Information in Data-Base Systems
Data relationships in recent information structuring models, however, essentially group and categorize data in some static fashion in the data base. But relationships can also be defined in a procedural fashion. An example of such an item is age. 'for example, to maintain a completely accurate value of someone's age, it would have to be updated continuously. Therefore, rather than assigning a particular stored Value to the data item age, it might be preferable to define it procedurally as current date minus data of birth. This leads directly to the idea that a model of information should allow not only static, grouping relationships.

Print on DemandSeller: Forgotten Books, London, United Kingdom
Seller rating 5 out of 5 stars
Paperback. Condition: New. Print on Demand. This book explores the nature of information in data base systems. It presents a model of information as a collection of functions that produce values in response to arguments. Virtual information unifies data, algorithms, and their combinations, providing alternative methods to meet requests for information. The book identifies classes of virtual information useful in resolving the issues of representation and materialization. The functional model and virtual information have significant implications for data base systems, improving system performance and offering a conceptually simple, yet consistent view of many formerly disparate issues. This book will be of interest to researchers and practitioners in the field of data base systems. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
