Abstract

A method and apparatus for persisting object oriented data are provided in various embodiments. Persistent storage is established for a working data set and a committed data set. The areas for the working and committed data sets are used for storage of the persistent data objects. After a persistent data object is updated in computer memory, the updated version is written to the working data set. Then, references to the working data set and the committed data set are switched, whereby the working data set becomes the committed data set and the committed data set becomes the working data set.
