Oracle

Best database company in the world.

It's going to be around for a while.

It's a place where "knowledge is power". Therefore, people hold on to what they know and prefer not to share it. Otherwise, you'll know what they know, and they won't be "better". The rating system helps to enforce this.

No one wants to share information or work together in case you might become better than they are.

Cut out the rating system.

Stop rewarding the folks who have been there forever.

Listen to the newer folks and share the bonuses, stock, and projects.
