I am little bit confused between whether to insert XML file as it is or
insert data from the XML file in to a particular field from the table.
I will decided it depending upon the performance factor
For storing the XML file as it is, will there be any performance cause if
compared to storing values in particular fields.
If performance issue is not there for XML formats then we have around 12 to
13 tables,
if we store XML data as it is in all tables then is there any generic format
for select query?
Thanks
