    Definition and Types
    • NoSQL databases store data in non-tabular format instead of relational tables
    • Five main types: document, key-value, wide-column, graph, and in-memory
    • Document databases store semi-structured data in JSON-like documents
    • Key-value databases use unique keys paired with values
    • Column-oriented databases organize data in rows with varying column names
    • Graph databases store data as nodes with relationships between elements
    • In-memory databases provide ultra-low latency for real-time applications
    Key Features
    • Flexible schemas allow easy adaptation to changing data requirements
    • Horizontal scalability without downtime
    • High availability through distributed architecture
    • Faster queries without complex joins
    • Some support ACID transactions, others lack standard consistency
    Advantages and Limitations
    • Flexible data model and agile development capabilities
    • Better suited for large datasets and real-time applications
    • Less mature than relational databases with fewer tools
    • Limited data integrity compared to SQL databases
    • Not ideal for complex queries and joins
    Use Cases
    • SQL databases excel in structured data and transactional information
    • NoSQL databases preferred for global distributed user experiences
    • Common uses include mobile, web, IoT, and real-time analytics
