What are the advantages of nosql database over rdbms?
Answer / Vishal Kumar Tiwari
NoSQL databases offer several advantages over traditional Relational Database Management Systems (RDBMS) for certain use cases:
1. Scalability: NoSQL databases, like MongoDB and Cassandra, can handle large amounts of data and scale horizontally by adding more servers to the cluster. RDBMSs are typically limited in scalability and require vertical scaling.
2. Flexible Data Modeling: NoSQL databases have a flexible data model that allows for storing semi-structured or unstructured data, such as JSON documents or key-value pairs, without requiring the rigidity of traditional tables and schemas.
3. High Performance: NoSQL databases offer better performance for read-heavy or write-heavy workloads due to their ability to distribute data across multiple servers and optimize reads with indexing mechanisms like secondary indexes in MongoDB.
4. Horizontal Scalability: NoSQL databases can handle large amounts of data by distributing it horizontally across multiple servers, while RDBMSs require vertical scaling to increase performance.
