The document discusses Database as a Service (DBaaS) and how it can be used to create database snapshots called "Snapclones" with Oracle Enterprise Manager 12c. DBaaS allows database functionality to be delivered as a service, including self-service provisioning of database instances. Making Snapclones with DBaaS and EM12c involves taking snapshots of databases and provisioning copies on-demand using a profile and template. It reduces storage usage by over 90% compared to traditional cloning methods.
