Couchbase
Couchbase is a distributed NoSQL document-oriented database designed for high performance, scalability, and flexibility. It combines key-value and document data models with SQL-like querying (N1QL), offering features like full-text search, analytics, and eventing. It is commonly used in real-time applications requiring low-latency data access and high throughput.
Developers should learn Couchbase for building modern, data-intensive applications such as mobile backends, IoT platforms, and real-time analytics systems where scalability and low-latency are critical. It is ideal when you need a flexible schema, SQL-like queries on JSON data, and built-in caching to reduce database load. Use cases include e-commerce, gaming, and content management systems that handle large volumes of unstructured or semi-structured data.
