SQL QuickStart Guide: The Simplified Beginner’s Guide To SQL by ClydeBank Technology is an introduction to Structured Query Language, a programming language used in databse management. I was not familiar with SQL prior to receiving this book, and I felt that this book was a great way to learn about this language. The authors include helpful charts to illustrate their points, and they also include an 18-term glossary page at the end to define important terms. The guide is 59 pages long, allowing it to provide a good deal of knowledge without the information being overwhelming. It is a nice book if you are wanting to jump into SQL!
