BaseX: Erweiterung einer nativen XML Datenbank um XQuery Update

This Bachelor Thesis describes concepts behind the extension of a native XML database with XQuery Update. BaseX is a compact and highly efficient open source XML database and XQuery processor. Based on a relational document encoding, a generic method is presented, that exploits the sequential encoding scheme to its full advantage. The implementation yields excellent test results. Further optimizations are proposed. A method to speed up the execution of critical structural updates and ways to accelerate the overall process. A discussion on ACID conformity in transactional XML database systems finalizes this work
