# Marketing definitions

Marketing definitions represent marketing activities such as campaigns or goals, and are managed by marketers. The following is true of all definitions:

- Definitions are represented by items in Sitecore.
- Definitions are created by marketers.
- Definitions are deployed to the [reference data store](https://doc.sitecore.com/xp/en/developers/93/sitecore-experience-platform/reference-data-service.html "Reference Data Service"). If a definition has not been deployed, it cannot be used in an xDB context such as processing.
- Every definition type has its own definition manager in the Marketing Operations API.

Marketing definitions give meaning to a contact’s interaction with a brand. For instance, downloading a brochure might trigger a goal and clicking a link on Facebook might enroll the contact in a campaign.

Refer to the Marketing Operations user documentation for more information about how to work with definitions as a business user.
