Core application - Temporal development feature
Workflows, Activities, and Workers form the core parts of a Temporal Application.
Workflows: A Workflow defines the overall flow of the application. You write it in your programming language of choice using the Temporal SDK. Conceptually, a Workflow specifies a sequence of steps and orchestrates the execution of Activities.
Activities: An Activity is a method or function that encapsulates business logic prone to failure (e.g., calling a service that may go down). The system can automatically retry these Activities upon some failures. Activities perform a single, well-defined action, such as calling another service, transcoding a media file, or sending an email message.
Workers: A Worker executes your Workflow and Activity code.
