What are the advantages of using a NoSQL database instead of an RDBMS?
One of the technologies solutions architects deal with frequently is databases. Therefore, you should have a deep understanding of the different types of databases and compare and contrast them. Knowing which type of database to use for a specific situation will demonstrate your qualifications for this role. If possible, you should try to determine which type of database the organization is currently using to emphasize this when answering these types of questions.
"While both NoSQL databases and RDBMS systems have their merits, each is more suited for a specific situation. NoSQL databases perform better in less structured environments where the data is volatile and constantly changing. They also work well for applications where the database activity is very high and horizontal scalability is required. NoSQL databases are also effective when dealing with large amounts of data in the range of terabytes and petabytes. The final advantage of NoSQL databases is that it is easier for developers to work with."
