By Noel Randewich REDWOOD CITY California (Reuters) – Oracle Corp Chief Executive Larry Ellison on Tuesday launched in-memory technology for speeding up data analysis in a bid to beef up demand for his companys software products. The technology will go on sale in July as an add-on to Oracles existing databases, Ellison said at an event at the companys headquarters. Its another whistle and bell that Ellison and Oracle can talk up to the customer base, said FBR analyst Daniel Ives. Thats what customers are focused on. For decades, Oracle has been seen as the gold standard for database technology, but it is under attack from smaller, aggressive companies like Salesforce.com and Workday offering competitive software and Internet-based products at prices that often undercut Oracle.
