Oracle database is mainly a product suitable for transation processing systems (OLTP) and it's got a dominant position in that market, a clear leadership. This market is almost saturated now with not much growth or expansion left in this area. Newer market for growth is datawarehousing (DWH) space where the growth is at the moment and it would be high growth area in forseeable future as corporations across the world try to make sense out of data stored in OLTP systems. Such DWH systems require huge storage capacity and huge data processing capabilities. Normally the database products suitable for OLTP are not suitable for DWH.
The leader in DWH space is Teradata which can store huge amount of data and has got huge processing capabilities as well. Netezza is another promising product in this area.
Oracle being such a agressive company currently has got no product in this area and Larry Elison would definitely not give a miss to such a growth-promising area. He would definitely try to enter into this area. Building a product from scratch would not be a feasible solution for him. So Larry would definitely try to gobble up any of existing product either Teradata , which is listing soon on bourses, or Netezza.
We would not be surprised if Larry does a hostile bid, like done many in recent past in ERP space, for any of these or any other such product in DWH area.
