NoSQL Schema Design
NoSQL schema design is the process of structuring data models for non-relational databases, such as document, key-value, graph, or column-family stores. It focuses on optimizing for scalability, performance, and flexibility by denormalizing data, embedding documents, or using relationships suited to specific query patterns. Unlike SQL's rigid schemas, it often involves iterative design based on application needs and access patterns.
Developers should learn NoSQL schema design when building applications that require high scalability, low-latency access, or handling unstructured or semi-structured data, such as in real-time analytics, content management systems, or IoT platforms. It is essential for leveraging the strengths of NoSQL databases like MongoDB, Cassandra, or DynamoDB, where schema flexibility and distributed performance are prioritized over ACID transactions.
