* Conceptual Design involves the creation of the use-case diagram, class diagram, and data dictionary.

* Physical Design focuses on implementation of the entities and relationships of the logical database model using a relational DBMS.

c) Implementation: The DBA is providing database access interfaces and programs.

d) Data loading: Involves initializing and pre-loading data into database tables.

e) Testing and validation: Includes functionality testing, load testing, and business logic validation.

f) Operation: The database is released to production and implemented.

g) Maintenance: Rounds out the cycle with performance tuning, data backup, and troubleshooting.
