If you're not a major data geek, you may not have heard of this yet. But Hadoop is a new data storage methodology that could basically upend the entire world of Big Data. It was created by the Goog (unsurprising) and nurtured by the open source community and Yahoo!. When Google and Yahoo! are working on something together, you KNOW it's big.
Hadoop allows for distributed computing around large data stores, where the data may not be in compatible formats. Lots of Big Data companies are using it now.
So it gets me thinking: how might this affect the AMS market? It's not going to happen today, obviously, but I think the database vendors need to be paying attention.
