Comparing XML Databases to Object Databases

[John Snelson]

I agree - this is basically the conclusion I came to. I think there are
a number of factors which give XML databases a better chance than object
databases had:

1) Ubiquity of XML - there's a lot of XML that needs storing.
2) The natural fit with the web, where it needs to be easy to handle 
XML/XHTML/HTML.
3) The presence of a good standard query language and data model.
4) The rise in interest to more closely combine program logic with query 
logic (LINQ etc.)
5) Increasing questioning of the relational model and one size fits all 
databases [1]
