ABSTRACT: 

With the increasing popularity of XML, there arises the need for managing 
and querying information in this form. Several query languages, such as 
XQuery, have been proposed which return their results in document order. 
However, most recent efforts focused on query optimization have disregarded 
order. This seminar presents a simple yet elegant method to maintain 
document ordering for XML data. Analysis of our method shows that it is 
indeed efficient and scalable, even for changing data. Finally I will also 
overview other research results that we recently obtained from my research 
group at UNSW.
