SimpleDB, one of Amazon.com's suite of online services that people can use to build Web sites or other computing operations, is out of private beta testing.

"We've made the business decision to go with SimpleDB even simpler than it was before. You can now get started for free. For at least the next six months, you can consume up to 500MB of storage, and you can use up to 25 machine-hours each month. You can transfer 1GB of data in, and another 1GB out," said AWS evangelist Jeff Barr in a blog posting Monday.
To make SimpleDB easier to use, Amazon said it plans to release a new interface similar to the SQL (Structured Query Language) widely used in databases today. It also plans a mechanism to let people more easily upload multiple items.
