9.6. Summary

At this point we have covered the basics and many of the details of space-based transactions. We've seen that transactions are a fundamental tool for providing failure semantics in distributed systems. Space-based transactions simplify the use of the more general Jini Transaction model and provide a means of grouping together space-based operations to ensure consistency. We also covered the mechanics of using a transaction manager to create and complete transactions.

At this point, rather than providing a more full-blown transaction-based example, we are going to move on to the next two chapters, both of which make use of transactions. There you will see the use of transactions in more fully developed examples.
