摘要

The subject invention provides a system and/or a method that facilitates tracking a data change to an entity within a data storage system at an entity level and at a sub-entity level. The data storage system can be a database-based file system, wherein an interface can receive at least one data change to an entity within the data storage system that in part represents complex instances of types. A track component can track additional data change information of one or more sub-entity levels of the entity when the entity participates in a synchronization (sync) relationship.
