Correctly close cursors and databases, use transactions.

[Xenega]

Best practice with cursors and databases is to always close in finally clauses. It's avoid to leak opened cursors or opened databases (cause of bug).
When updating multiple tables, best practice is to use a transaction to ensure data coherence (also improve the performance).

There's a typo in your code: transition <-> transaction. :)

In addition to that: We do not need to perform a transaction if we are just reading values (Beginning of AddServerActivity).

I like moving to the try/final pattern and having the transaction for adding identify and server in one atomic operation. Well done! :)
