ABSTRACT:
A group join query facilitates navigation of relationships (e.g., one-to-many or many-to-one) across a plurality of data collections. Such a query operator produces nested or hierarchical results that capture the arguments passed thereto. If desired, the nested results can be flattened to simulate conventional relational database results.
