SAP appears on track to release a version of its Hana in-memory database software that supports non-SAP software, claims Barclays. That would greatly expand the market for Hana, whose performance has led Bernstein to forecast sales will grow to $750M this year and reach $4.4B in 2015. Yesterday, Oracle (NYSE:ORCL) announced an upgrade for its Exadata line, which combines an in-memory database with powerful hardware. Larry Ellison boasted of huge performance gains, and (in typical fashion) dismissed Hana as "really small" by comparison.
