1. A method of storing and retrieving digital data comprising:
converting the digital data into one or more state transformation units (STUs); wherein an STU is read-only, of a variable size, and creates, modifies, or adds data added to a business object; storing state transformation units on a storage medium; retrieving a business object by reading and applying state transformation units associated with that business object; and further wherein STU's are characterized by one or more of the following: STUs are unmodifiable; STUs are self-identified where each STU has identifying information comprising a business object GUID to which that STU pertains and a timestamp; STUs can be copied anywhere in a linked distributed storage system without needing to synchronize data; STUs are independent in that one STU does not become a part of another STU; STUs are independent in that there is no dependency hierarchy for STU's. |
