Programmatic Interfaces

Every AWS SDK provides one or more programmatic interfaces for working with DynamoDB. These interfaces range from simple low-level DynamoDB wrappers to object-oriented persistence layers. The available interfaces vary depending on the AWS SDK and programming language that you use.

The following section highlights some of the interfaces available, using the AWS SDK for Java as an example. (Not all interfaces are available in all AWS SDKs.)
