* A transaction handle uniquely identifies a transaction on the storage backend.

* All modifications to the storage backend must occur within the context of a single
* transaction. Such a transaction is identified to the JanusGraph middleware by a StoreTransaction.
* Graph transactions rely on the existence of a storage backend transaction.
* <p/>
* Note, that a StoreTransaction by itself does not provide any isolation or consistency guarantees (e.g. ACID).
* Graph Transactions can only extend such guarantees if they are supported by the respective storage backend.
