We show that there is a model  mismatch between group communication and database, and because of this,  classical group communication systems cannot be used to build 2-safe database replication.   We propose a new group communication primitive called end-to-end atomic broadcast   that solves the problem, i.e., can be used to implement 2-safe database replication.   We also introduce a new safety criterion, called group-safety, that has  advantages both over 1-safety and 2-safety.  Experimental results show the gain of efficiency of group-safety over lazy replication,  which ensures only 1-safety.
