Abstract
In this paper we provide an overview of XML-processing functions that are currently supported by the so-called 'Big Three', i.e. Oracle 11g, IBM DB2 9, and Microsoft SQL Server 2008.
We firstly show what are the key aspects a user may require from an XMLenabled database. Then, we provide an overview of their support in the respective systems.
And, finally, we compare and contrast the findings so that advantages and disadvantages of the particular systems are apparent.
