// Amazon SimpleDB is a web service providing the core database functions of
// data indexing and querying in the cloud. By offloading the time and effort
// associated with building and operating a web-scale database, SimpleDB provides
// developers the freedom to focus on application development.  A traditional,
// clustered relational database requires a sizable upfront capital outlay,
// is complex to design, and often requires extensive and repetitive database
// administration. Amazon SimpleDB is dramatically simpler, requiring no schema,
// automatically indexing your data and providing a simple API for storage and
// access. This approach eliminates the administrative burden of data modeling,
// index maintenance, and performance tuning. Developers gain access to this
// functionality within Amazon's proven computing environment, are able to scale
// instantly, and pay only for what they use.
//
//  Visit http://aws.amazon.com/simpledb/ (http://aws.amazon.com/simpledb/)
// for more information.
//The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
