The demand for SQL information and training continues to grow with the need for a database behind every website capable of offering web-based information queries. SQL is the de facto standard for database retrieval, and if you need to access, update, or utilize data in a modern database management system, youwill need SQL to do it. TheSecond Editionof "Joe Celko's Trees and Hierarchies in SQL for Smarties" covers two new sets of extensions over three entirelynew chapters and expounds upon the changes that have occurred in SQL standards since the previous edition's publication. Benefit from mastering the challenging aspects of these database applications in SQL as taught by Joe Celko, one of the most-read SQL authors in the world. *Expert advice from a noted SQL authority and award-winning columnist who has given 10 years of service to the ANSI SQL standards committee
*Teaches scores of advanced techniques that can be used with any product, in any SQL environment
*Offers graph theory and programming techniques for working around deficiencies and gives insight into real-world challenges
This book provides a great overview on graphs, trees, and hierarchies, and then several great examples of how to work with them in a Relational Database enviroment. A particular strength of the book is that it balances being a "Cookbook", providing useful code snippets to work with the structures, but also explaining the how and why of each of the snippets.
I am looking forward to using many of the methods in ongoing projects; as well as looking forward to researching some of the other topics (petri nets, state transition graphs) further.
While I just scanned it for a project at work. I was very impressed with the structure and presentation. Very easy to understand and presented the material excellently.
