However, its extensive feature set is really built upon upon a core infrastructure resulting from sound architectural decisions made very early on that have stood the test of time. This core infrastructure manages transactions and the ability to commit and roll back changes, protects the integrity of the database, enables backup and recovery, and allows for scalability to thousands of users all accessing the same data. \u003c\/p\u003e  \u003cp\u003eMost performance, backup, and recovery problems that database administrators face on a daily basis can easily be identified through understanding the essential core of Oracle Database architecture that Lewis describes in this book. \u003c\/p\u003e  \u003cul\u003e  \u003cli\u003eProvides proven content from a world-renowned performance and troubleshooting expert \u003c\/li\u003e  \u003cli\u003eEmphasizes the significance of internals knowledge to rapid identification of database performance problems \u003c\/li\u003e  \u003cli\u003eCovers the core essentials and does not waste your time with esoterica \u003c\/li\u003e  \u003c\/ul\u003e  What you’ll learn\u003cul\u003e  \u003cli\u003eOracle's core architectural foundations \u003c\/li\u003e  \u003cli\u003eHow much overhead is reasonable \u003c\/li\u003e  \u003cli\u003eHow to recognize when you're doing too much work \u003c\/li\u003e  \u003cli\u003eHow to predict bottlenecks and why they will happen \u003c\/li\u003e  \u003cli\u003eHow to minimise contention and locking \u003c\/li\u003e  \u003cli\u003eWhy concurrency can slow things down significantly \u003c\/li\u003e  \u003c\/ul\u003e  Who this book is for      \u003cp\u003e     \u003cem\u003eOracle Core: Essential Internals for DBAs and Developers \u003c\/em\u003eis aimed at database administrators ready to move beyond the beginning stage of doing work by rote towards the mastery stage, in which knowledge of what needs to be done comes not from a set of recipe-style instructions, but rather from the intimate knowledge and understanding of the system to be managed.
