Illustrates some use cases for Oacle pluggable databases in development environments

1. Use Cases for
Oracle Pluggable Databases
in Development Environments
Concepts not restricted to Oracle Databases

2. Oracle Multitenant Architecture
«The multitenant architecture enables an Oracle database to function as a
multitenant container database (CDB).»
«A CDB includes zero, one, or many customer-created pluggable databases
(PDBs).»
«A PDB is a portable collection of schemas, schema objects, and nonschema
objects that appears to an Oracle Net client as a non-CDB. All Oracle databases
before Oracle Database 12c were non-CDBs.»

3. Advantages of Multitenant Architecture for Development
§ A pluggable database behaves just like a regular database
§ Allows dynamic creation and deletion of pluggable databases
§ Pluggable databases can easily be cloned
§ No need to use container technologies like docker
– can be an advantage

BASE database can define
for instance all required DB
schemas

5. Use Case #2 – Share DB-States Within a Team

6. Use Case #3 – Snapshot DB-State (Objects and Data)
and Use It repeatedly

Same concept as using a «database service» in CI which is spin up as docker instance
