Its like the "audit" facility on a system I've recently seen. ins/upd/del on every single table - every single row change logged to a single audit table which (in order to handle all tables) has columns (renamed to preserve anonymity)

id    number         (surrogate key)
dt    date           (timestamp)
typ   varchar        (ins/upd/del)
ta    varchar2       (tablename)
c1    varchar2(2000)  first column of table 

c2 varchar2(2000) next column of table c3 varchar2(2000) next column of table ...
...
c200 varchar2(2000) next column of table

So now there's several hundred million records in there...Also a bit of bummer that pretty much any kind of analysis query simply never comes back within reasonable time frames (if it all...).

Thus its data stored that will never be read :-)
