Rudolph van Graan is Giving the Following Talks
Mnesia and Postgres

Financial systems present a particularly difficult problem in terms of scalability because by implication you have shared data.  The presentation focuses on how we at PMT achieve scalability and redundancy using a combination of Mnesia, PostgreSQL and Oracle Hardware.
