SimpleDB Component
Properties Methods Events Configuration Settings Errors
The SimpleDB Component provides an easy interface to Amazon's SimpleDB.
Syntax
nsoftware.InAmazon.Simpledb
Remarks
The SimpleDB Component allows you to access Amazon's SimpleDB. SimpleDB allows you to create globally accessible databases on Amazon's servers. These databases can be used by developers to transfer data between distributed applications and store information. A brief synopsis follows, but please refer to Amazon SimpleDB documentation for details.
You will first need to sign up for the SimpleDB service and obtain the AccessKey and SecretKey from Amazon. Then you can start creating domains in your account using CreateDomain. You can then start adding items and attributes to the queue using PutAttributes and retrieve the same using Select.
There are other methods such as ListDomains, DeleteDomain, DeleteAttributes etc. that further enable you to manage your SimpleDB domains and items.
