| Outline of Final Research Achievements |
In this research, context-preserving fusion has been developed. So far, fusion transformation works only for side-effect free languages. However, XQuery, which is a query language to XML data, has a side-effect when it is typically used in data integration settings. Most of real world entities can be represented in graph structures. XQuery can handle graph structures. In this work, a sound context-preserving XQuery fusion has been developed. Also, the class of the queries and the schema has been investigated to show the completeness of the fusion.
