It depends how dynamic your data will be and how complex your
queries will be.
If it is just 50 updates per day and you are doing retrieving
you data based on simple <key,value> pair queries using XML
will be the best idea.
If it comes to more complex queries and issues like concurent
writing, record locking and transaction rates > 1 transaction
per min. i would always recommend the usage of a real relational
database like posesql via ODBC(e.g. see http://gnade.sourceforge.net).
