The second paragraph of the story "Oracle chief leaves to join London-based Big Data firm," posted Friday, incorrectly identified one of Dr Andy Piper's former employers. He has also previously worked at BEA Systems.
The story has been corrected on the wire and the second paragraph now reads:
Piper had been leading development in Oracle Complex Event Processing, as well as driving global product strategy and innovation. He has also previously worked for BEA Systems.
