In the Splunk AppDynamics application model, a business transaction (BT) represents an end-to-end, cross-tier processing path used to fulfill a request for a service provided by the application.

The business transaction is a key component for effective application monitoring. It consists of all required services within your environment such as login, search, and checkout that are utilized to fulfill and respond to a user-initiated request. These transactions reflect the logical way users interact with your applications. For example, activities such as adding an item to a shopping cart and then checking out various applications, databases, third-party APIs, and web services.
