Google Blogoscoped breaks the news on the launch of Google Base. Apparently Google Base is a database that you can use to upload anything to - and Google will store it for you and index it.
What makes this more interesting than say, Furl.net or other storage services? It's Google, of course! They are setting up base so the following equation will work:
Base + Froogle + Wallet = Amazon
Or eBay or Yahoo Stores.
Base is a key piece of infrastructure in Google's grand online store system.
