     * Sends a command to an Amazon QLDB ledger.
     *
     * Instead of interacting directly with this API, we recommend using the QLDB driver or the QLDB shell to execute data transactions on a ledger.
     * + If you are working with an AWS SDK, use the QLDB driver. The driver provides a high-level abstraction layer above this *QLDB Session* data plane and manages `SendCommand` API calls for you. For information and a list of supported programming languages, see [Getting started with the driver](https://docs.aws.amazon.com/qldb/latest/developerguide/getting-started-driver.html) in the *Amazon QLDB Developer Guide*.
     * + If you are working with the AWS Command Line Interface (AWS CLI), use the QLDB shell. The shell is a command line interface that uses the QLDB driver to interact with a ledger. For information, see [Accessing Amazon QLDB using the QLDB shell](https://docs.aws.amazon.com/qldb/latest/developerguide/data-shell.html).
