CQRS Update with Udi Dahan
While at the NSBCon in Brooklyn, New York, Carl and Richard talk to Udi Dahan about CQRS. CQRS is the acronym for Command and Query Responsibility Segregation. Udi begins the conversation talking a bit about the history of CQRS and how it derived from Bertrand Meyer's work on CQS back in the 80s. The cornerstone of CQRS is a separation between commands (insert/update/delete) and querying in databases - not just relational databases, of course, but certainly the focus is there. The power of the pattern is its ability to handle huge volumes of data in both directions, simplifying application design as the load increases. Great thinking from Udi as usual!
