Oracle Buys Siebel

Oracle to acquire Siebel Systems for $5.85B: Larry Ellison is either going to rule the world, or he’s setting himself up for a massive fall.

The deal further bolsters Oracle’s aggressive drive to overtake SAP as the world’s largest maker of business applications software — the computer coding that automates a wide range of administrative tasks.

In the past nine months, Oracle has either completed or announced five takeovers of business applications software makers, an expansion that has cost more than $17.6 billion so far.
