All from the perspective of users. Like getting help from someone senior. This book organizes all the examples well and explains almost line by line.
Yet, it is all focused on programming, unlike The Little SAS Book, which is more focused on explaining how things work in SAS. It talks about more advanced materials than The Little SAS Book.
Thus, it should be more useful as a working companion. If you really want learn SAS well, maybe you should start from The Little SAS Book and then this book. In fact, I use this book to review and I am going to read The Little SAS Book again to complete this review. It works perfect for this use. You can start slowly and then just read the codes and look for explanations for any questions you may have.
I learned SAS from this book when I got my first SAS programming job. By using this book I quickly became a quality Data Analyst that was contributing to the company. Skim, study, read and practice the skills in this book and you will have very strong SAS skills.
Really nice and quite complex introduction strongly focused on examples and practical solutions. Perhaps the most useful guide I've found for SAS. As "advanced" topics provides also basics (and only basics) of SQL (proc sql) and SAS macros.
