The inspiration for the material contained in this book comes from my experiences developing Oracle software, and from working with fellow Oracle developers to help them build reliable and robust applications based on the Oracle database. The book is basically a reflection of what I do every day and of the issues I see people encountering each and every day. I covered what I felt was most relevant, namely the Oracle database and its architecture. I could have written a similarly titled book explaining how to develop an application using a specific language and architecture—for example, one using JavaServer Pages that speaks to Enterprise JavaBeans, which in turn uses JDBC to communicate with Oracle. However, at the end of the day, you really do need to understand the topics covered in this book in order to build such an application successfully. This book deals with what I believe needs to be universally known to develop successfully with Oracle, whether you are a Visual Basic programmer using ODBC, a Java programmer using EJBs and JDBC, or a Perl programmer using DBI Perl. This book does not promote any specific application architecture; it does not compare three tier to client/server. Rather, it covers what the database can do and what you must understand about the way it works. Since the database is at the heart of any application architecture, the book should have a broad audience. As the title suggests, Expert Oracle Database Architecture concentrates on the database architecture and how the database itself works. I cover the Oracle database architecture in depth: the files, memory structures, and processes that comprise an Oracle database and instance. I then move on to discuss important database topics such as locking, concurrency controls, how transactions work, and redo and undo, and why it is important for you to know about these things. Lastly, I examine the physical structures in the database such as tables, indexes, and datatypes, covering techniques for making optimal use of them.
