Probably the best bet would be to write the individual attributes to respective
database columns. It keeps a few things simpler. It would also allow you to
update the database from multible sources (many threads, or many users on the
database).
Other wise, you would have to serialize the object to a binary object and write
that to the BLOB field. When you imported it back, you would have to
deserialize. Some languages call this pickeling. As I have not touched C++
code for a while, I'm not sure what classes are availible to do this for you.
The BLOB way of doing it would force you read/write the entire thing everytime
you update the object, unless you are just using the database to store it for
backup.
