Oracle Database Administration from Zero to Hero - Oracle Database Multitenant Architecture (part 1 of 2)

The video tutorial explains Oracle's multi-tenant architecture, introduced in Oracle Database 12c. It covers the differences between Container Databases (CDB) and Pluggable Databases (PDB), the components of multi-tenant architecture, and how to create and manage PDBs. The tutorial also discusses the structure of instances and databases, the role of root and seed containers, and the data dictionary's organization. The multi-tenant architecture allows for efficient database management and is mandatory from Oracle Database 21c onwards.
