Event stores enable us to perceive other 'dimensions’ of data. Object oriented datastores run the risk of losing valuable state transition information. The CQRS design pattern distinguishes between mutable commands and immutable queries, allowing different data stores to be used by the systems respective responsibilities. Event stores work perfectly for persisting command - and resulting event - data. Current state can be generated by hydrating the set of historical events onto an initial state, keeping state transition data intact, and informative.
