Object Oriented Database vs Relational Database

NEC
(Semiconductor Manufacturing)

NEC, the second largest semiconductor manufacturer in the world, has deployed its integrated manufacturing (CIM) system, the NEC Object-Oriented and Open (O3) system, based on an ODBMS. Currently used to manage a distributed environment including 16 factories worldwide, O3 represents NEC's migration from the mainframe to open systems, skipping the now declining RDBMS generation and leaping ahead to ODBMS.

According to Shuji Imura, General Manager of NEC's Semiconductor Group Information Systems Center:

"The O3 System is a triumph in implementing object oriented technology in a business critical application. Objectivity/DB has enabled the O3 system to increase our productivity and accelerate time-to-market, giving NEC a significant competitive advantage and increased market share."
