Be aware that this book is not formatted like other O Reilly books Fonts are very small and text lines are very long which makes it physically unpleasant to readIt s written in a very old fashioned and verbose way Things that could be written in a few words take several sentences The author uses a lot of parenthesis asides and foot notes so the text doesn t flow nicely you constantly have to switch between different levels of importance I couldn t read it beyond the fourth chapter I did learn a few relational concepts but the author fails to show how that can apply to real world problems His general approach is rather negative He really wants to show that SL products don t implement relational theory correctly and are inherently broken He sounds like the whole world is mistaking but only him knows the truth it and is unfairly misunderstood He keeps using the same running example a suppliers and parts database It s a simplistic example with only three tables but he doesn t clearly explains what business problem this example is intending to solve so I couldn t understand how he came up with that example Tables and columns are named the old fashioned way using all uppercase abbreviation such S SNO PNO TY etc which obviously doesn t help to follow his explanationsI ll leave two stars because the author obviously knows his stuff and if you have a lot of spare time and patience you might be able to read this book from cover to cover and maybe get some value out of it Please reply to this comment if you feel that I m missing something
