The Transcoop Transaction Model

This chapter describes the TRANSCOOP cooperative transaction model CoACT, and its underlying paradigm of cooperative work. As motivated in Chapter 4 new application areas of the transaction concept impose new requirements on transaction models. In all of the discussed application areas there is a need to support the cooperation of human actors engaged in common tasks and working towards a common goal. a transaction model supporting cooperation should make the sharing and exchange of information among co-workers as natural as possible while still preserving a notion of consistency.
