Mapping XML to a Wide Sparse Table
... For example, if a new element d2 is inserted as d1’ssibling, the link between B and D evolves to a one-to-manyrelationship. The sparse mapping only needs to insert a newrow, whereas conventional relational storage would partitionT2(B; D) into two tables T4(B); T5(D). (Inserting a new rowdoes change ...
