#Database Design

Design an end-to-end system encompassing: - Candidate-led requirement gathering (functional and non-functional requirements). - Definition of entities, DB schema, relationships, constraints, and cardinality with justifications. - Detailed API design including request and response schemas for all core endpoints. - High-level architecture and inter-service communication. - In-depth discussion of microservice patterns including Circuit Breaker, Saga, CQRS, and Event-Driven architecture.
