Learning SQL ON PostgreSQL

SQL as a language is more vital than ever. There are very few Information Technology jobs that do not interact with databases on a fundamental level, and while there are many ways to facilitate that interaction, SQL remains the most flexible, powerful, and useful tool.This book uses a context-driven, hands-on approach to provide a thorough introduction to SQL in most of its aspects. After completing this book and its exercises, a student should have a solid foundation in SQL. They should be able to apply this knowledge to a variety of situations and be able to expand upon their knowledge.
