chema-less or Flexible Schemas: Many NoSQL databases do not require a predefined schema, allowing for dynamic data structures and easier adaptation to changing requirements. Some offer flexible schemas where different documents or records can have varying attributes.
Different Data Models: NoSQL encompasses various data models beyond the relational table, including document, key-value, graph, and column-family.
Horizontal Scalability: NoSQL databases are often designed for distributed architectures, making horizontal scaling (adding more servers) easier and more cost-effective.
BASE Properties (in contrast to ACID): Many NoSQL databases prioritize malaysia whatsapp mobile phone number list availability and eventual consistency over strict ACID properties:
Basic Availability:
Soft State: The state of the system may change over time, even without input.
Eventual Consistency: The system will eventually become consistent after a period of no updates, but reads might not reflect the most recent writes immediately.
The system is generally available and responds to requests
