it does not upset the scheme.  You need to store the data in some format or 
other for Promath.  some sort of XML could be that format.

like you said: in sql-db

if you were to store the XML in flat textfiles, you can extract with XQL or 
sgrep or other standard tools for extracting XML being developped these days.

if you store it in an sql-db, then first extract it via sql and then maybe 
apply XQL if needed.

flat textfiles are slow if huge compared to sql-db.  :-)
