Difference between RDBMS and NoSQL DBMS

Difference between Relational Database Management System (RDBMS) and NoSQL Database Management System (DBMS)

Relational Database Management System (RDBMS) is a traditional type of database that organizes data in tables with rows and columns, and enforces relationships between tables. Examples include MySQL, PostgreSQL, Oracle.

NoSQL Database Management System (DBMS) is a newer type of database that can store and manage unstructured or semi-structured data. It does not require a fixed schema and can scale horizontally. Examples include MongoDB, Cassandra, Redis.

Scenarios for using RDBMS:

  • When data has a well-defined structure and relationships
  • When ACID (Atomicity, Consistency, Isolation, Durability) compliance is important
  • When the application requires complex queries and transactions

Scenarios for using NoSQL DBMS:

  • When dealing with large volumes of unstructured data
  • When flexibility in data model is crucial
  • When scalability and high availability are top priorities
