"I highly recommend terrific book recounting why Oracle's merger became the disaster it was, "High-Tech Planet: Secrets of an IT Road Warrior" was written by a former Oracle executive who bares it all in this no-holds-barred description of the business culture that allows fraud, insider trading, outlandish revenue projections and product roadmaps, manipulation, deceit, and various legal and accounting schemes as part of a corporate acquisition.
I think I remember that the first few chapters can be read for free from Amazon"
