Backend data is received from a computer program product such as a hard disk or other long term data storage. The backend data is structured using nodes that are associated with a unique identifier such as a GUID. The nodes are addressable using the unique identifier, and backend data items are associated with corresponding addressable nodes such that the backend nodes can be quickly accessed. Front-end data can be received from a computer program product such as a hard disk or other long term data storage. The front-end data is structured using nodes that are associated with a unique identifier such as a GUID. The nodes are addressable using the unique identifier, and front-end data items are associated with corresponding addressable nodes such that the front-end nodes can be quickly accessed.
