I don't claim to be an expert, but my understanding was that the goal of
a data warehouse was to make a repository of information that could be
plumbed through essentially relational queries -- demographic
information, correlations between dates and so forth. I don't see the
benefit of including document data in this sort of repository. As
someone else mentioned, XML may well be a good transfer format for the
information to move it FROM the regular databases into the data
warehouse.
