      This report presents a framework of integrated transaction and session 
      management to meet the requirements of applications based on group work.
      Transaction management is provided in order to guarantee data consistency
      and recovery from failures with the additional benefit of structuring
      complex applications as nested transactions. Visibility between users is
      achieved by allowing unfinished work to be transferred between users
      or by establishing a synchronous session. Within a session users can update
      shared objects in turns and be notified of others' actions synchronously.
