Oracle Design (Nutshell Handbooks)by Dave Ensor
Synopses & Reviews
Oracle Design looks thoroughly at the field of Oracle relational database design. The design of both databases and applications is an often neglected area of Oracle, but one that has an enormous impact on the ultimate power and performance of a system. If the initial design is poor, then the most powerful hardware, the most sophisticated software tools, and the most highly tuned data and programs won't make your system run smoothly and efficiently. Indeed, applications that have been designed poorly will never be able to perform well, regardless of the tuning and retrofitting performed later on.There are three main areas of Oracle design:
Book News Annotation:
Covers database, code, and architecture design for the Oracle operating system. The text is arranged in four sections including an overview of Oracle and data modeling; aspects of database design including denormalization, data types, nulls, keys, indexes, temporal data, import/export, backup, recovery, security, archiving, and audit; examples of architecture design issues for client/server, distributed databases, data warehouses, and parallel processing; and aspects of code design including metrics and prototypes, locking, and the design of screens, reports, batch programs, online help text, and navigation.
Annotation c. Book News, Inc., Portland, OR (booknews.com)
Covering database, code, and architecture design for the Oracle operating system, this text is arranged in four sections including an overview of Oracle and data modelling; and aspects of database design including denormalization, data types, nulls, keys and indexes.
This book focuses exclusively on Oracle database design. It covers the most up-to-date Oracle issues and technologies, including massively parallel processors, very large databases, data warehouses, client-server, and distributed database. The design advice is detailed and thorough. The book delves deeply into design issues and gives advice that will have a major impact on your database and system performance.
About the Author
Dave Ensor spent over 35 years in IT, almost all of it in a hands-on role as a programmer, a designer, or a researcher into the performance characteristics of specific pieces of software. He worked with Oracle databases for 15 years in all three of these roles, also building a worldwide reputation for his ability to present technical material with clarity and humor. He is coauthor of the books "Oracle Design" and "Oracle8 Design Tips", and he's an Honorary Oracle9"i" Certified Master. Dave holds undergraduate degrees in both mathematics and law.
Stevenson is Carlson Professor of Psychiatry and Director of the Division of Personality Studies at the Health Sciences Center, University of Virginia.
