# Share data securely

Data in Domino is reusable across Projects, and each data method carries its own permissions: sharing a Project does not automatically expose its data. The four data methods use related but distinct access models:

* **Datasets** use [Dataset roles](/cloud/platform-capabilities/core-concepts/data/sharing-and-security/share-datasets): the Dataset owner grants roles (Reader, Editor, Owner) to users and organizations, and the role decides who can view, edit, or manage the Dataset. Datasets originate inside a Project but can then be shared with any Project or user in Domino.
* **NetApp Volumes** use [role-based permissions similar to Datasets](/cloud/platform-capabilities/core-concepts/data/netapp-volumes/create-netapp-volumes#add-users-or-organizations-to-netapp-volumes): the Volume owner grants Reader, Editor, or Owner roles to users and organizations. NetApp Volumes differ from Datasets in that they are global from the start (they aren't scoped to a single "home" Project), so their permissions travel with the Volume, not with any one Project.
* **Data Sources** use [credentials and visibility](/cloud/platform-capabilities/core-concepts/data/sharing-and-security/share-data-sources): access depends on how the Data Source authenticates (individual credentials or a shared service account) and whether it's shared with everyone or with specific users and organizations.
* **External Data Volumes (EDVs)** are [administrator-controlled](/cloud/platform-capabilities/core-concepts/data/sharing-and-security/share-edv): an administrator decides which users and groups can access each volume.
