"Amazon SimpleDB is a web service for running queries on structured data in real time. This service works in close conjunction with Amazon Simple Storage Service (Amazon S3) and Amazon Elastic Compute Cloud (Amazon EC2), collectively providing the ability to store, process and query data sets in the cloud."
"The data model used by Amazon SimpleDB makes it easy to input, manage and query your structured data. Developers organize their data-set into domains and can run queries across all of the data stored in a particular domain. Domains are collections of items that are described by attribute-value pairs."
.. SQL is getting old and boring .. it's time for a new database .. and unconfirmed rumor says that the service is written in Erlang .. interesting ..
