Conclusions
- Neither pessimistic consistency nor optimistic consistency
solve the data replication problem in the mobile computing environment.
- One reduces data availability and the other
does not provide a good data model to the user.
- View consistency built on an optimistic replication substrate
provides a user-dependent consistent view of data,
without significantly affecting availability of data.
- It is a useful consistency model for various different types of
entities.
- Large scale distributed applications, distributed workgroups
and especially mobile computing will directly benifit from it.
