A transaction definition based on message passing

In object oriented databases (OODB) all interactions among objects are via messages. A message can be viewed as a command to activate a specific method within the object to which the message is sent. The paper motivates and proposes an OODB transaction definition based on message passing. It first describes several previous OODB transaction definitions and identifies requirements for a transaction definition based on message passing. Then it provides an introduction to transaction trees, a view of an OODB transaction. A more formal definition of a transaction tree is then given, followed by an indication of areas for future research.<
