ABSTRACT:
A database shadowing system for performing data checkout/checkin operations. The system includes performing the steps of 1) identifying a data item stored in a database for editing, 2) copying the data item from the database to an active memory file thereby creating an active memory copy of the data item, 3) associating a tag with the active memory copy of the data item, changing a state of the data item 4) tag depending upon the edit operation performed on the active memory copy of the data item, and 5) saving any change made to the active memory copy of the data item by making the change to the database data item upon issuance of a save command, so that the data item tag of the active memory copy of the data item controls the manner of changing the database data item.
