| 摘要 |
The invention relates an apparatus for returning a data item to a requester. (The requestor may for example be a systems application.) A request is received by the apparatus to access a data item having data contents of uncertain state (i.e. because the data item is pending completion of a transaction.) The apparatus obtains the data item contents and an indication of the state (e.g. delete_on_commit) of the data item contents. This information is then returned to the requester.
