It's product independently to Key-Value, Document, Column Graph and DBs. Very good and accessible in my opinion, for consistency, persistence, scale, distribution models, Map-Reduce and schema migration will be discussed. Always stand developer productivity and the demands of 24x7 and Big Data in the foreground. The only 150 pages are a boon to the world of information overload. The rather complex and often theoretically represented field of distributed systems is factual, accurate, free presented by academic exaggeration and therefore ideally suited for the "Practitioner" or "Professional".
While you no longer have to imagine Martin Fowler, I want Pramod Sadalage emphasize co-wrote the book "Refactoring Databases" (if you want to fool you that schema changes during operation are not possible, I highly recommend reading).
The book is a clear buy, especially if you look at, for example, want to quickly learn as an IT manager, an overview of the interesting field of knowledge. Who has already come with one of NoSQL products into contact, can make its expertise available in the context. Programmers certain NoSQL variants, the book certainly provide too little depth and theoretically it is more likely to call the match. However, it is precisely what the title promises, namely a distillate of NoSQL paradigm.
