Record locking using Vector

[Steve Brailsford]

Hi All,
I have a few concerns on the server side.
1. How could I control the updates through the Vector say when one client is using a different database to another client.
2. Is the server suppose to be for one database?
3. When requests come in from the same client, does the server how would the server know not to create a new Data object previously created with the database location.
Thanks in advance.
Steve
This I feel is my last hurdle to overcome before submission.

Don't make the problem more difficult than descibed in the assignment. The server should just use one database. Any client connecting to that server would use a common database.
