Oracle has appointed former Microsoft CFO Gregory Maffei as its third concurrent president. He will also take on the chief financial officer (CFO) role from July.

Maffei's responsibilities will include legal, human resources, manufacturing and distribution departments, and global real estate, the company said.

Oracle already has two presidents: Safra Catz and Charles Phillips. Catz had been acting CFO since March and was named president in January 2004. She will remain president and is responsible for global operations.

Phillips joined the company in May 2003, and became president of Oracle in January 2004. He has responsibility for global field operations including consulting, marketing, sales, alliances, channels, customer programs, and corporate strategy.

Maffei's appointment will not affect the responsibilities of Catz and Phillips, according to an Oracle spokesman. Oracle will continue to have three presidents, each focusing on different aspects of the company's operations, he said.

Maffei joined Microsoft in 1993 and took over as CFO in July 1997, leaving in January 2000 to become chief executive officer of 360Networks.
