We are designing an application that needs to use
a relational database to hold quite a large amount
of data.

In particular there is one table that has about 33
fields, 18 indexes, and 120 bytes per record.
Additionally, we are going to need to add about 2
million records per day to the table, delete about 2
million records per day from the table, hold 2 weeks
worth of data within the database (approx. 30 million
records), and sustain an average add rate of about 23
records per second while, at the same time, sustaining
an average delete rate of 23 records per second.

My questions are, what database software should we use,
what kind of hardware platform will be needed to
support the specifications enumerated above, and what
kind of average query performance can we expect?
