:: Norman May
In my thesis I have studied the optimization and efficient evaluation of XQuery queries.
These results are part of the Natix-Projects.
In 2007 I joined SAP AG.
First I did research and served as technical coordinator in the Theseus/TEXO research project. Since 2010 I contribute to the development of the SAP in-memory platform.
