  "documentation":"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. <p> 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. </p> <p> Visit <a href=\"http://aws.amazon.com/simpledb/\">http://aws.amazon.com/simpledb/</a> for more information. </p>",

The client may specify new attributes using a combination of the <code>Attribute.X.Name</code> and <code>Attribute.X.Value</code> parameters. The client specifies the first attribute by the parameters <code>Attribute.0.Name</code> and <code>Attribute.0.Value</code>, the second attribute by the parameters <code>Attribute.1.Name</code> and <code>Attribute.1.Value</code>, and so on. </p> <p> Attributes are uniquely identified in an item by their name/value combination. For example, a single item can have the attributes <code>{ \"first_name\", \"first_value\" }</code> and <code>{ \"first_name\", second_value\" }</code>. However, it cannot have two attribute instances where both the <code>Attribute.X.Name</code> and <code>Attribute.X.Value</code> are the same. </p> <p> Optionally, the requestor can supply the <code>Replace</code> parameter for each individual attribute. Setting this value to <code>true</code> causes the new attribute value to replace the existing attribute value(s). For example, if an item has the attributes <code>{ 'a', '1' }</code>, <code>{ 'b', '2'}</code> and <code>{ 'b', '3' }</code> and the requestor calls <code>PutAttributes</code> using the attributes <code>{ 'b', '4' }</code> with the <code>Replace</code> parameter set to true, the final attributes of the item are changed to <code>{ 'a', '1' }</code> and <code>{ 'b', '4' }</code>, which replaces the previous values of the 'b' attribute with the new value. </p> <p> You cannot specify an empty string as an attribute name. </p> <p> Because Amazon SimpleDB makes multiple copies of client data and uses an eventual consistency update model, an immediate <a>GetAttributes</a> or <a>Select</a> operation (read) immediately after a <a>PutAttributes</a> or <a>DeleteAttributes</a> operation (write) might not return the updated data. </p> <p> The following limitations are enforced for this operation: <ul> <li>256 total attribute name-value pairs per item</li> <li>One billion attributes per domain</li> <li>10 GB of total user data storage per domain</li> </ul> </p>"
