NoSQL Database Types

NoSQL databases are optimized for flexibility, scalability, and performance, making them ideal for Big Data and real-time applications. They are categorized based on how they store and access data:

Key-Value Stores

Store data as simple key-value pairs. Ideal for caching, session storage, and high-speed lookups.

• Redis
• Amazon DynamoDB

Columnar Stores

Store data in columns rather than rows, optimized for analytical queries and large-scale batch processing.

• Apache HBase
• Apache Cassandra
• Amazon Redshift

Document Stores

Store semi-structured data like JSON or BSON documents. Great for flexible schemas and content management systems.

• MongoDB
• Amazon DocumentDB

Graph Databases

Use nodes and edges to represent and traverse relationships between data. Ideal for social networks, recommendation engines, and fraud detection.

• Neo4j
• Amazon Neptune

Tip: Choose the NoSQL database type based on your data access patterns and application needs.

Not all NoSQL databases solve the same problem.
