| Would the basics of SQL querying be useful to you, but you dont want to start at the very beginning? Do you wish you had an easy way to ramp up quickly to get a basic understanding of key features and capability? Then you need this book! Without a ton of conceptual information or general programming basics you already know, this book is a quick guide for computing professionals and programmers to learn the basics--and more--in an easily digestible way.
The value of the relational database is indisputable. It is by far the most commonly used,
modern database system. The primary language for relational databases is SQL, making
it the gateway to the data of the small business and corporate enterprise. Many of the
applications that you see on the Internet, in your local library, and so on, access and
manipulate their data using SQL.
We wrote this book for technically competent readers who want a short, focused, and inexpensive
introduction to the main features of SQL. Our general approach revolves around
creating the resource we have wished for in our classes. We believe that this book is
appropriate for both students and professionals.
This is not a guide to using a specific database product. We assume that you have
a database system installed and sufficient access privileges to perform the operations
described in this book. There are many database products readily available if you do
not have access to an existing one. Many such systems are available for download from
the Internet for trial or even free use. See the book Web site (http://www.mkp.com/
practical/sql) for a partial list of products.
About the Authors:
Michael J. Donahoo is an associate professor at Baylor University. He teaches undergraduate database courses and has worked as a database consultant.
Gregory Speegle is an associate professor and graduate director at Baylor University, where he has taught graduate and undergraduate database courses for more than ten years.

IBM Lotus Domino: Classic Web Application Development Techniques
Creating web pages was fairly straight-forward—in the early 1990's. Today, there are many, often competing technologies available for creating a web experience. Remarkably, all these differing technologies and strategies interoperate in a relatively seamless way to serve the billions of people who use the World Wide Web and the... | | The Rohonc Code: Tracing a Historical Riddle
First discovered in a Hungarian library in 1838, the Rohonc Codex keeps privileged company with some of the most famous unsolved writing systems in the world, notably the Voynich manuscript, the Phaistos Disk, and Linear A. Written entirely in cipher, this 400-year-old, 450-page-long, richly illustrated manuscript initially gained... | | Pragmatic Unit Testing in C# with NUnit (Pragmatic Programmers)Learn how to improve your C# coding skills using unit testing. Despite it's name, unit testing is really a coding technique, not a testing technique. Unit testing is done by programmers, for programmers. It's primarily for our benefit: we get improved confidence in our code, better ability to make deadlines, less time spent in the debugger, and... |
