Oracle just recently announced it's 11g monster. Here is Joe McKendrick's take on it. My take is that it's great for consultants, there will be lots of money to be made trying to implement this beast. It's bad news for companies trying to implement it.
The corporate IT mantra is keep it simple, keep it quick and deliver a lot of value to the business. There is nothing simple about 11g and with the Sun acquisition things will only get more complex.
