Algorithms for translating view updates to database updates for views involving selections, projections, and joins

This paper addresses the question of updating relational databases through XML views. Using query trees to capture the notions of selection, projection, nesting, grouping, and heterogeneous sets found throughout most XML query languages, we show how XML ...

A large number of analytical queries (e.g., all the 22 queries in the TPC-H benchmark) are based on acyclic foreign-key joins. In this paper, we study the problem of incrementally maintaining the query results of these joins under updates, i.e., ...

Database views are extensively used to represent unmaterialized tables. Applications rarely distinguish between a materialized base table and a virtual view, thus, they may issue update requests on the views. Since views are virtual, update requests on ...
