Object Oriented Database vs Relational Database

American Meter
(Process Control)

American Meter developed a system for brokering and distributing electrical power and gas in real time. With the recent deregulation of these industries, their system has led the way. Originally, they spent two years developing the application with a leading RDB MS, but in beta test they discovered that it was far too slow for production use. Fearing product failure, they decided to try converting to an ODBMS, Objectivity/DB. In three months they were in production, exceeding performance targets. Even better, in the process of conversion, they were able to discard one third of the application code, which had been needed for mapping to the RDBMS. This project won a finalist award at the Object World, San Jose, 1996, shortly after it shipped.
