Defined and inserted state seed data (e.g., Tamil Nadu, California, Ontario) with attributes such as name, code, and associated country.

Added city seed data (e.g., Chennai, Los Angeles, Toronto) linked to their respective states.

Built seeder scripts that automatically populate the database with state and city data during setup or migrations.

Ensured correct relational mapping between countries → states → cities in the seeded dataset.

Verified seeded values appear in the application grid, supporting dropdowns, filters, and master data views.

Coordinated with developers/testers to keep location seed data updated and aligned with application requirements.
