Abstract
Data versioning in a non-volatile memory. An object key associated with a data object is created. An index into an object table is generated using the object key. A version number is stored in conjunction with the data object stored in the non-volatile memory. In an object linked-list, the object key and the location information of the data object in the non-volatile memory are stored. A record associated with the data object is created in an object table. The record includes an index, a reference to the object linked-list, and the version number. The index is generated based on the object key.
