Contributions

The two main contributions of this report are:

• A new distributed file system with support for mobile computing.
• Guidelines for implementing a transactional facility there upon.

The fulfillment of the goals for the distributed file system is discussed in Section 8.2.

As for the guidelines for a transactional facility--I have

• given my ideas to which properties the transactions should have,
• specified a new algorithm for optimistic concurrency control,
• specified transaction primitives, and
• given a rich example of how I foresee the transactions used.
