Why Read This Book? When you opened the cover of this book, you had a notion of what you would find. With a title like Beginning Oracle Programming, it's fairly obvious what this book is all about. Simply put, the purpose of this book is to teach you how to manage data using an Oracle database. The goal of Beginning Oracle Programming is to introduce you to those concepts that are important to understand as a beginning-level Oracle user. You are setting out on the same journey we traveled some years ago. We know the things you are going to run into time and time again. We understand the challenges you are going to meet when you have to develop an application or administer your database. We can guarantee you that the techniques you'll learn in this book are proven and have led us through many successful implementations. So instead of talking about the things we want to teach you in an abstract kind of way, let's talk specifics.

This is the newest edition of Apress's best-selling book on Oracle Database. Previous editions and incarnations of this book have sold in excess of 20,000 units. The book is written by Tom Kyte, who is universally known and respected in the world of Oracle.

"e;THINK."e; In 1914, Thomas J. Watson, Sr. joined the company that was to become IBM, and he brought with him this simple one-word motto. It was an exhortation to all IBM employees, no matter their role, to take care in decision-making and do their jobs with intelligence. "e;THINK"e; soon became an icon, appearing on publications, calendars, and plaques in the offices of many IT and business managers within and outside IBM, and even in The New Yorker magazine cartoons. "e;THINK"e; was a good idea in 1914, and it is a good idea now. "e;Think different."e; More recently, Apple Computer used this slogan in a long-running advertising campaign to revitalize the company's brand, and even more important, to revo- tionize how people think of technology in their daily lives. Instead of saying "e;think differently,"e; suggesting how to think, Apple's slogan used the word "e;different"e; as the object of the verb "e;think,"e; suggesting what to think (as in, "e;think big"e;). The advertising campaign emphasized creativity and creative people, with the implication that Apple's computers uniquely enable innovative solutions and artistic achievements. When I joined Oracle Corporation (then Relational Software Incorporated) back in 1981, database systems incorporating the relational model were a new, emerging technology.

Oracle Database Transactions and Locking Revealed provides much-needed information for building scalable, high-concurrency applications and deploy them against the Oracle Database. Read this short, 150-page book that is adapted from Expert Oracle Database Architecture to gain a solid and accurate understanding of how locking and concurrency are dealt with by Oracle Database. Also learn how the Oracle Database architecture accommodates user transactions, and how you can write code to mesh with how Oracle Database is designed to operate.Good transaction design is an important facet of highly-concurrent applications that are run by hundreds, even thousands of users who are all executing transactions at the same time. Transaction design in turn relies upon a good understanding of how the underlying database platform manages of the locking of resources so as to prevent access conflicts and data loss that might otherwise result from concurrent access to data in the database.Oracle Database Transactions and Locking Revealed covers in detail the various lock types, and also different locking schemes such as pessimistic and optimistic locking. Then you’ll learn about transaction isolation and multiversion concurrency, and how the various lock types support Oracle Database’s transactional features. You’ll learn some good tips for transaction design, as well as some bad practices and habits to avoid. Coverage is also given to redo and undo, and their role in concurrency. This is an important book that anyone developing highly-concurrent applications will want to have handy on their shelf.
