Another completely subjective opinion: when people talk about large or very
large databases (VLDB) they usually refer to the amount of data, not the number
of tables or views. For example, a database that occupied 50 GB would be
considered large even it had a dozen tables (most likely with a few of those
having millions of rows). Conversely, a database with 500 tables but occupying
only 1/2 GB would likely be considered small or medium.
