NoSQL is better than RDBMS because of the following reasons/properities of NoSQL:
- It supports semi-structured data and volatile data
- It does not have schema
- Read/Write throughput is very high
- Horizontal scalability can be achieved easily
- Will support Bigdata in volumes of Terra Bytes & Peta Bytes
- Provides good support for Analytic tools on top of Bigdata
- Can be hosted in cheaper hardware machines
- In-memory caching option is available to increase the performance of queries
- Faster development life cycles for developers
Still, RDBMS is better than NoSQL for the following reasons/properties of RDBMS:
- Transactions with ACID properties – Atomicity, Consistency, Isolation & Durability
- Adherence to Strong Schema of data being written/read
- Real time query management ( in case of data size < 10 Tera bytes )
- Execution of complex queries involving join & group by clauses
