The author, Michael, acknowledges the help of many fine people in contributing to his book on creating a full social web application for movie enthusiasts using Spring Data Neo4j. The book covers both a narrative tutorial and a thorough reference to the graph facilities available in Spring Data Neo4j, including core concepts, querying, and simple annotated POJO programming model. It also introduces two alternative facilities: Neo4jTemplate and entity repositories, which offer convenient APIs for working with the Neo4j graph database and extend existing techniques of working with annotations and object mapping.
