Written with the least effort, just a few general guidelines without worthy technical tip. You may have thought like me that it is cheap anyway and it is worth to have a short, well-written introduction before diving into the details. This book would not fill the bill:
1) It is not well written, it shows no practical example or tutorial;
2) It has nothing particularly smart to teach you; the examples it gives for the macros are very poor.
So basically you will have to pay GBP 20 anyway for a good book (like Access The Missing Manual) if you want to do anything decent with Access. That book will teach you the same as this one, but is better written, and is much more complete with plenty of important matters and practical examples to follow.
