On the relational side, we propose a mild condition on SPJ views, and show that under this condition the analysis of deletions on relational views becomes PTIME while the insertion analysis is NP-complete.
We develop an efficient algorithm to process relational view deletions, and a heuristic algorithm to handle view insertions.
The interaction between XPath recursion and DAG compression of XML views makes the analysis of XML view updates rather intriguing.
In addition, many issues are still open even for relational view updates, and need to be explored.
