Systems and/or methods for performing atomic updates on large xml information sets

Abstract

Certain example embodiments described herein relate to techniques for processing XML documents of potentially very large sizes. For instance, certain example embodiments parse a potentially large XML document, store the parsed data and some associated metadata in multiple independent blocks or partitions, and instantiate only the particular object model object requested by a program. By including logical references rather than physical memory addresses in such pre-parsed partitions, certain example embodiments make it possible to move the partitions through a caching storage hierarchy without necessarily having to adjust or encode memory references, thereby advantageously enabling dynamic usage of the created partitions and making it possible to cache an arbitrarily large document while consuming a limited amount of program memory. Such techniques may be extended to enable atomic updates to be processed efficiently, e.g., by maintaining commit level information in a partition list and optionally implementing document shadowing.
