I have serious doubt that a native XML database, however
well
designed it is, can succeed in commercial space, and ultimately as a viable technical solution. Look at OODB, no matter what reason you attribute its failure to. Why don't we focus our energy on implementing XML data structure on a relational database and map all desired features to RDBMS features? I love to see a standard like that. We can definitely map the tree structure of XML into
relational
database and store an offset (of the element in the blob) going with the element, ..., blah, blah. As long as the XPath navigation can be efficiently supported, I guess other features would not be such a hard thing. The so-called multi-dimensional database is so well fitted
in
RDBMS.
Yes, it takes up much space. Storage is cheap, isn't
it?
