Paperback. Condizione: New. Print on Demand. This book presents a detailed study of distributed database systems and computer networks, offering a comprehensive model for their optimization. The author considers simultaneously the distribution of computation power, the allocation of programs and databases, and the assignment of communication lines, providing a more complete perspective than previous works in the field. The model developed by the author incorporates set-up costs and the return flow of information, addressing practical concerns often overlooked in other studies. Additionally, the author introduces a novel "Bounded Branch and Bound" algorithm, a powerful mathematical programming technique capable of solving large-scale integer nonlinear programming problems. This algorithm is more efficient than existing methods and can handle problems with nonlinear objective functions and constraints, making it applicable to real-life scenarios with set-up costs. The book concludes by discussing the significance of the model and the insights it provides, highlighting its relevance in the design of distributed systems and computer networks. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Taschenbuch. Condizione: Neu. Neuware - In 'The Entity-relationship Model: A Basis for the Enterprise View of Data,' Peter P.S. Chen presents the foundational concepts of the Entity-Relationship (ER) model. This seminal work, originally published in 1976, introduces a high-level data model designed to facilitate database design and data management within organizations. Chen's ER model offers a structured approach to representing data entities, attributes, and relationships, providing a clear and intuitive framework for understanding and organizing complex data structures. The book explores the principles behind the ER model, illustrating how it can be used to create a comprehensive enterprise view of data. It emphasizes the importance of effective communication between database designers, users, and managers, and demonstrates how the ER model can serve as a common language for defining data requirements and designing robust database systems.
