I have a database that is currently just over 60GB. The largest table has 214 million rows. Two other tables have a total of 127 million records between them(I am looking at the primary key generator value which is shared between those two tables). I have learned to be VERY careful with the commands I issue: "select count(*)" is a bad bad bad thing to do.... However, with carefully constructed queries and indices, retrievals range from very quick (sub-second accesses) to slow but livable (a few minutes to find and retrieve a few thousand rows out of 214 million).
