Amazon SimpleDB
Wednesday, February 13, 2008 
This looks super cool... Amazon is preparing an online database that you can use with ease. SimpleDB is a database built on Erlang that is accessed via REST and SOAP calls.
- CREATE a new domain to house your unique set of structured data.
- GET, PUT or DELETE items in your domain, along with the attribute-value pairs that you associate with each item. Amazon SimpleDB automatically indexes data as it is added to your domain so that it can be quickly retrieved; there is no need to pre-define a schema or change a schema if new data is added later. Each item can have up to 256 attribute values. Each attribute value can range from 1 to 1,024 bytes.
- QUERY your data set using this simple set of operators: =, !=, <, > <=, >=, STARTS-WITH, AND, OR, NOT, INTERSECTION AND UNION. Query execution time is currently limited to 5 seconds. Amazon SimpleDB is designed for real-time applications and is optimized for those use cases.
- Pay only for the resources that you consume.
