# Key concepts in Duaer

In Duaer a digital organization is the canvas flow, and a digital employee is the side that delivers a result. Nodes, credentials, expressions, and plans are on this page.
## Digital organization

A digital organization is the set of nodes on the canvas that finishes one job. It starts at a trigger and follows the connections. The saved record is still called a workflow in some product identifiers.

## Digital employee

A digital employee is a delivery you hand to Duaer. You name the result, Duaer does the work, and you accept it. Schedules hang off a digital employee. Refer to [Schedule a task for a Duaer digital employee](/advanced-ai/digital-employee-schedules.md).

## Node and canvas

A node is one step: a trigger, a fetch, a transform, or a send. The canvas is where you place and connect nodes. Refer to [Work with nodes in Duaer](/Duaer-Organizations/components/nodes.md).

## Credential

A credential is stored on the Duaer instance and protected by the encryption key. A node references the credential instead of putting the secret in a parameter. Refer to [Create and edit credentials in Duaer](/credentials.md).

## Expression and execution

An expression fills a parameter at run time inside {{ }}, such as a field on the current item or $now. An execution is one recorded run of the digital organization. Success, error, and canceled all stay in the executions list.

## Plan and AI credits

Hosted plans are Hobby, Starter, Pro, and Business. One full run of a digital organization counts as one execution. AI credits are a separate allowance for model calls. Refer to [Duaer plans and credits](/manage-cloud/plans.md).

## Duaer orgifyDesk

Duaer orgifyDesk is the assistant on the canvas. It edits the digital organization at the nodes you name. Refer to [How Duaer orgifyDesk edits a digital organization](/advanced-ai/assistant-edits.md).
## Questions

### In Duaer, is a digital organization the same thing as a digital employee?

No. A digital organization is the flow on the canvas. A digital employee is the delivery you accept. Schedules belong to the digital employee.
