NoSQL is designed to expand transparently to take advantage of new nodes and is built using low-cost hardware, so costs should not be a problem. Big Data In today's world, transactions are so frequent that the data generated by these transactions is enormous. It is very difficult to store this huge transactional data in traditional database systems. NoSQL with its elastic scaling feature, you can scale up your database to store huge amounts of transactional data. All the challenges of processing this huge transactional data can be overcome with NoSQL database systems. No DBA Required NoSQL database systems can handle a lot of things on their own. There is no need for dedicated database administrators to manage day-to-day database operations. Since these systems have simpler data models, automated repairs etc., no administrator is needed to manage these things. Economy Traditional databases cost more. The amount of space you get by purchasing traditional database systems is less than the NoSQL database system. In other words, the cost per gigabyte per second or transaction per second is many times lower than the traditional database management system. Flexible Data Model NoSQL database systems have flexible data models, unlike traditional relational database management systems. Any changes to the data model in traditional database systems may cause the entire database system to hang or functions may not work as expected. But this is not the case with NoSQL database system. NoSQL has a much more relaxed data model that allows the user to add a new column to store data without much hassle. The NoSQL key value stores and documents the database virtually in a data
