This book is the first that approaches the challenges associated with graphs from a data management point of view; it connects the dots. As I am currently involved in building a native graph database engine, I encounter problems that arise from every possible aspect: data representation, indexing, transaction support, parallel query processing, and may others. All of them sound familiar to a database researcher, but the inherent change is fundamental as they originate from a new foundation. I found that this book contains a lot of timely information, aiding my efforts. To be clear, it does not offer the blueprint for building a graph database system, but it contains a bag of diamonds, enlightening the readers as they start exploring a field that may fundamentally change data management in the future.
