CQRS: Command Query Responsibility Segregation
Jason Gerard and I were talking about document databases the other day, and he said "Have you heard about CQRS?" This was news to me, so I started doing some research. Wikipedia, which usually provides good information, said the following "CQRS is simply the creation of two objects where there was previously only one. The separation occurs based upon whether the methods are a command or a query (the same definition that is used by Meyer in Command and Query Separation, a command is any method that mutates state and a query is any method that returns a value)."
