Well, not really.  

More specifically, on a fundimental level a database will provide a
number of predefined data types that it will deal with gracefully (int,
date, money, char, etc).  In order to gain some of the advantages of a
database, such as ease of access to the data from other applications,
you really need to use these data types.

Of course, you can store any arbitrary binary data in a database engine,
it's called a BLOB in modern parlence.  But what's the point ?  You have
to have special code to deal with it.

As I mention above, I disagree.
