Aggregate versus connected data models
Data can be modeled in Neo4j using both connected and aggregated forms. The connected form has the advantage that new dimensions can be easily extracted from the same model. In comparison, the aggregate form (also can be called as MapReduce) can give us quick access to the aggregated result, which is very useful in particular. In this recipe, you will learn both data models and a third one also, which has been derived by combining both of these data models.
