I do not claim the creation of the transaction log + snapshot concept. Databases have forever used transaction logs for persistence purposes. Several multiplayer games use the concept of publishing the users' "transactions" and having a replica for every user calculating the entire game state.

What I did was to recognize its full potential, give it a name (SystemPrevalence), provide a free implementation (Prevayler) and start a community around it. @:)



I have put some (constructive) criticism of the Prevayler.org site over on my blog.
