....to decide upon materialization of intermediate results as views, and (4) Query processing of updates issued on XML views that wrap relational data by decomposing the updates into SQL update statements and consistency checks on the relational base data. The Rainbow System. We have extended Rainbow [1], our existing XML data management system, as shown in Figure 1. Rainbow accepts an XQuery query or an update request in an extended XQuery syntax from the user. The XQuery is parsed into an algebraic representation, called XML Algebra Tree (XAT) 3] The XAT is then optimized by the global query ....

....Order, Rainbow. 1 Introduction 1.1 Problem Description XML views are a popular technique for integrating data from distributed and heterogeneous data sources. Many systems employing XML views, often speci ed by the XML query language XQuery [27] have been developed in recent years [4, 15, 30, 31]. Materialization of the view content has many important applications including providing fast access to complex views, optimizing query processing based on cashed results, and increasing availability. Materialization however raises the issue of how to eciently refresh the content of views in this ....
