/**
 * Client for accessing AmazonSimpleDB.  All service calls made
 * using this client are blocking, and will not return until the service call
 * completes.
 * 

* Amazon SimpleDB

* 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/ * for more information. *

* The PutAttributes operation creates or replaces attributes in an * item. The client may specify new attributes using a combination of the * Attribute.X.Name and Attribute.X.Value * parameters. The client specifies the first attribute by the parameters * Attribute.0.Name and Attribute.0.Value , the * second attribute by the parameters Attribute.1.Name and * Attribute.1.Value , and so on. *

*

* Attributes are uniquely identified in an item by their name/value * combination. For example, a single item can have the attributes * { "first_name", "first_value" } and { "first_name", * second_value" } . However, it cannot have two attribute * instances where both the Attribute.X.Name and * Attribute.X.Value are the same. *

*

* Optionally, the requestor can supply the Replace * parameter for each individual attribute. Setting this value to * true causes the new attribute value to replace the * existing attribute value(s). For example, if an item has the * attributes { 'a', '1' } , { 'b', '2'} and * { 'b', '3' } and the requestor calls * PutAttributes using the attributes { 'b', '4' * } with the Replace parameter set to true, the * final attributes of the item are changed to { 'a', '1' } * and { 'b', '4' } , which replaces the previous values of * the 'b' attribute with the new value. *

*

* NOTE: Using PutAttributes to replace attribute values that do * not exist will not result in an error response. *

*

* You cannot specify an empty string as an attribute name. *
