Oracle PL/SQL by Example
This book is not intended as a comprehensive SQL Developer book. Rather, the focus is SQL.
Therefore, you need to understand the basics of the tool within the context of SQL. The purpose of this book is not to describe and point out every menu option but to teach you the SQL language. SQL Developer is a productivity tool that makes you a more efficient and proficient user of the language. You still need to know and understand your actions, and the tools can eliminate some basic mistakes and alleviate some frustrations for a beginning user.
Therefore, you will gain some basic knowledge of this tool as part of the exercises in this book. You can choose to perform most of the exercises in either tool, depending on your preference. Throughout this book, you access data from a sample schema called STUDENT, which contains information about a computer education program. The schema was designed to record data about instructors, courses, students, and their respective enrollments and grades.
After you download the installation files to create the schema within your Oracle database, you will be able to follow the exercises in the book. Several conventions used in this book help make your learning experience easier. These are explained here. Note - This icon denotes advice and useful information about a particular topic or concept.
