## 28. Tasks

The Tasks section of the Dashboard currently has three tabs:

- Apps
- Definitions
- Executions

## 28.1 Apps

Apps encapsulate a unit of work into a reusable component. Within the Data Flow runtime environment Apps allow users to create definitions for Streams as well as Tasks. Consequently, the Apps tab within the Tasks section allows users to create Task definitions.

Note: You will also use this tab to create Batch Jobs.
