No. 19: Oracle
As a vendor of choice when it comes to databases and enterprise applications, Oracle acquired Sun and gained a foothold in hardware. The company has now integrated the Sun technology into its product lines, most notably through the Exadata, Exalogic and Oracle Database Appliance offerings. With its lower-end wares, Oracle is expanding aggressively in the channel, reworking channel compensation and operations to make it easier to do business with Oracle.
