Description
Learning SQL: A Step-By-Step Guide Using Oracle is a brief, hands-on tutorial covering the basics of using SQL, as well as using the Oracle database engine with SQL. It assumes no previous knowledge of programming or databases.
The book focuses on providing an introduction to beginning SQL tasks. Throughout the chapters, readers are taken through various beginning aspects of SQL. At the end of each chapter, a series of exercises is provided to facilitate the practice of these newly learned skills. Throughout the book, common pitfalls and style tips are called out in margin boxes. With this book, readers learn not only the basics, but also gain insight into how these skills are used by professional Oracle programmers.
This book is appropriate as a main textbook in an Introduction to Oracle/SQL course, or as a supplemental book for an Introduction to Database course for CS, CIS, MIS, or IT students.
