Inside Relational Databases [Paperback]

(For the first edition)Quite simply - superb. By making relational databases understandable, Mark Whitehorn and Bill Marklyn have achieved far more than most.

Reviews from the first edition of Inside Relational Databases: "Quite simply - superb. By making relational databases understandable, Mark Whitehorn and Bill Marklyn have achieved far more than most. Making the subject interesting and entertaining as well puts these two authors firmly in a class of their own." - Neil Fawcett, Group Technical Editor, VNU Business Publications "PCW and Amazon.co.uk contributor Mark Whitehorn is that rare combination - an expert in his field, databases, and a fine writer too, with a talent for honing a complex subject down to its essentials." - Tamsin Todd, Computer & Internet Editor, Amazon.co.uk "Inside Relational Databases is excellent. It is clearly and concisely written and full of humorous asides which ease the reader through an otherwise weighty topic. Probably the most engaging technical book I have read." - Paul McGowan

The second edition of this best-seller is revised and updated. It delivers a reader-friendly explanation of the relational model and its importance to database designers and builders. Clear explanations make use of examples rather than equations, and show how an understanding of the relational model can lead to making a database faster and flexible. Topics covered include: nulls, primary and foreign keys, joins, relationships, domains, indexing, and many others. The authors manage to shed light on this tricky subject with substance and style.

Marklyn and Whitehorn cover essential relational database theory and explain how to build databases securely - seeking to do this without bagging the reader down with too much detail and endless formulae. They start by explaining interface components and letting the reader build working databases. Along the way the authors guide the reader through potential disasters and provide the techniques to avoid them. The text seeks to bridge the gap between theoretical database books and manuals.

Inside Relational Databases was first published in 1997 and, rather to our surprise, rapidly reached the status of a classic work in the database field. Translated into three other languages and sold all over the world, it has helped thousands of people to understand the relational model that underpins all modern databases. Inside Relational Databases has never been about how to use a particular database engine (Access, SQL Server, MySQL, whatever). Instead, it’s about the underlying way in which relational databases work. However it is very convenient if the book illustrates the relational model using the reader’s favorite product – such as Access. So, for the new edition we produced several different versions of the same book, each version based on a different database engine. The version in your hand is based around Access (hence the title). There are other versions based around SQL Server and MySQL. You shouldn’t buy this book if you are looking for a book about how to use Access. You should buy this book if you have created databases but they don’t seem to work very well. Perhaps you: •can’t retrieve the information that you want. •have to type in the same information over and over again. •type in data and it appears to go missing. •ask questions and get answers that you know are wrong. •can use Access but you don’t know exactly what to do with it. •know that a relational database lets you create multiple tables in the database but you are uncertain why this is to your advantage. Or perhaps you hear words in connection with databases like: •normalization •functional dependency •inner join •union •redundant data •data dictionary •meta-data •ER modeling •transaction •concurrency •locking You haven’t got the faintest idea what they mean and there is no one you can ask. We have also taken the opportunity of the new edition to restructure the book significantly. I (Mark) continue to teach database design and practice, both to undergraduates and in the commercial world. Without doubt the most popular topic in the commercial world is how to make databases run faster (no great surprise there) so we have added an entire section of brand new material (more than 10% of the entire book) on that topic. The section on designing databases has been reorganized and expanded and we also re-read the entire book (several times) and brought it all up to date. --This text refers to an alternate Paperback edition.

Dr. Mark Whitehorn has an extensive understanding of relational database theory and his popular and long running database column in the UK's Personal Computer World has already made database theory accessible to thousands. Bill Marklyn has an intimate knowledge of relational databases and was the Development Manager who oversaw the entire design of the first two major releases of Microsoft's highly successful database product, Access. Together they make a great team, illuminating a tricky subject with substance and style.
