| Abstract | XML projection is one of the main adopted optimization techn iques for reducing memory consumption in XQuery in-memory engine s. The main idea behind this technique is quite simple: given a query Q over an XML document D, instead of evaluating Q onD, the queryQ is evaluated on a smaller document D′ obtained fromD by pruning out, at loading-time, parts of D that are unreleva nt for Q. The actual queried document D′ is a projection of the original one, and is often much smaller than D due to the fact that queries tend to be quite selective in general. While projection techniques have been extensivel y investigated for XML querying, we are not aware of applications to XML updating. T he purpose of the paper is to investigate a projection based optimization mec hanism for updates. |
