It's
certainly quite possible to store graphical data in the form of XML documents in
an XML database such as Software AG's Tamino. For example, you can encode the
graphics as SVG, and storing the documents is then just like storing any other
XML documents.
The
question is, is this the best way of storing the data? The answer to that
depends, I think, on what kind of queries and manipulations you want to do. If
you want to do spatial queries, for example (find all restaurants within 5 miles
of here), then you may need the specialised indexing that comes with spatial
databases, which is not normally available in a relational or XML
database.
But I
think storing vector graphics in an XML database is probably a very good
strategy where the primary requirement is to retrieve the graphical information
"as stored", rather than to manipulate it and query it within the
database.
