    ///  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.
