Abstract
A method, apparatus, and article of manufacture for a computer implemented modification system for supporting localized data changes in a computer. A change is executed to data in a computer having a local database. The change is performed by the computer to modify data in the local database stored within a data storage device at the computer. The change is indicated as being global. When the local database on the computer is synchronized with a main database on another computer, only global changes are transmitted from the local database to the main database.
Claims42
A method of localizing changes in a computer, the method comprising the steps of:
- executing a change to data in a computer having a local database, the change being performed by the computer to modify data in the local database stored within a data storage device at the computer;
- indicating whether the change is a global change;
- and
- when the local database on the computer is synchronized with a main database on another computer, transmitting only global changes from the local database to the main database.
An apparatus for localizing changes, comprising:
- a computer having a data storage device that stores a local database;
- and
- one or more computer programs, performed by the computer, for executing a change to data in the computer, the change being performed by the computer to modify data in the local database, for indicating whether the change is a global change, and, for, when the local database on the computer is synchronized with a main database on another computer, transmitting only global changes from the local database to the main database.
An article of manufacture comprising a computer program carrier readable by a computer and embodying one or more instructions executable by the computer to perform method steps for localizing a change, the method comprising the steps of:
- executing a change to data in a computer having a local database, the change being performed by the computer to modify data in the local database stored within a data storage device at the computer;
- indicating whether the change is a global change;
- and
- when the local database on the computer is synchronized with a main database on another computer, transmitting only global changes from the local database to the main database.
