ABSTRACT:
Embodiments of the invention are generally directed to a method and system for processing 1:N relationships between data object nodes. A first data object and a second data object is provided wherein a first node of the first data object has a 1:N relation with a second node of the second data object. The first node includes a first sync key uniquely identifying a field in the first node. The second node includes n second sync keys, each of the n second sync keys uniquely identifying a field in the second node. A shadow node is generated in the first data object. The 1:N relation is de-normalized to generate 1:1 associations between the first node and the second node, the 1:1 associations being stored in shadow node.
