MongoDB and Redis are both NoSQL databases, but they have different data models and use cases. MongoDB uses a document-oriented data model, where each document can have varying schema fields and nested subdocuments. It is designed for handling unstructured and semi-structured data. On the other hand, Redis is a key-value store that primarily focuses on high performance in-memory data operations. It is used for caching, real-time analytics, and messaging.
