This image shows the concept of compartments. In the tenancy in Oracle Cloud Infrastructure, the root compartment contains a virtual machine instance, a virtual cloud network, block volumes, and Oracle Cloud Infrastructure Identity and Access Management (IAM) resources (for example, users, groups, and policies). The root compartment is automatically created when the tenancy is created. In the Frankfurt region, three compartments are used: Project A, Project B, and Finance. The Project A compartment contains resources for Project A, including a Payroll database instance and block volumes. The Project B compartment contains resources for Project B, including a Budgeting database instance and block volumes. Because the same users work on Projects A and B, the two databases are registered in Oracle Data Safe to the same compartment - Finance. An Oracle Data Safe sensitive data model named Sensitive Data Model 1, is also saved to the Finance compartment. Notice that you don’t have to register target databases to the same compartment in which they reside.
