A store is the data access interface for entities.
A store combines a projection, a stream reader, and two levels of caching: an in-memory cache, and an optional on-disk cache.
Entities are retrieved from the store without having to directly actuate a projection. The stream reading and projecting and caching are all transparent to the client code. To the developer, interacting with a store appears like interacting with any entity-centric data retrieval object, hiding the event-stream nature of the storage medium from the client code.
