What are the different types of the DBMS with the advantages and disadvantages?
Some common types of DBMS are relational, NoSQL, and NewSQL. Relational databases are structured and use SQL for querying, offering ACID compliance and strong consistency, but may struggle with scalability for large datasets. NoSQL databases are non-relational, offering flexibility and scalability for big data applications, but may lack ACID compliance and require more effort for data consistency. NewSQL databases combine the best of both worlds, providing ACID compliance, scalability, and performance for complex queries, but can be more complex and expensive to implement.
