From the reviews: "I would recommend it primarily to database practitioners and database implementers seeking to better understand the physical layer of in-memory database systems. ... The material will be of interest to database developers interested in physical-layer implementation. It may also be of some interest to application developers working with in-memory databases, particularly SanssouciDB." (S. Thomas, Computing Reviews, September, 2013)
