No matter, whether it is servers, computers or mobile devices, it is impossible to think of any application including games, mobile apps or websites without the use of the ability of machines.
Over time, SQL and NoSQL have been an excellent invention in the area of data management. They have been used to store data or big data and retrieval smooth and optimized. Moreover, it is also difficult to choose one and completely go with other alternative.
Apart from these differences, Subham Abrol wrote this most up-voted answer on Stackoverflow.
Structured data plays an important for the business, as they will always have to store customer and financial information. Over the last few years, companies have started to maintain more unstructured data that generally they are deploying and scaling applications.
Moreover, they have more content like podcasts, PDFs, videos, and images that they are using on their website, for social media and emails. SQL is a better option for low-complexity applications that raised over time.
There is some complex application that used SQL technologies for their applications such as Real-time big data analytics, Mobile Transactions, E-auctions, E-Commerce, Online Retailers, Dynamic pricing, Group buying offerings, Automated online assistants, and so on.
If you want real-time analytics (and ability to tweak it with new stats time by time) – SQL will definitely work better for you than MongoDB.
SQL databases is better option for data reliability and safe guarantee of performed transactions.
Relational database management systems are very popular and it is very easy to get free as well as paid support from such systems. In case, any issue arises, it becomes much easier to solve than recently-popular NoSQL databases – especially when solution is bit difficult in nature.
Complex querying and data keeping requirements provide solution on the go with relational databases. They are much more best and well-organized in this domain.
Undoubtedly, NoSQL delivers advantages to business, especially startups and small business that can advantages from leveraging free open source software. However, NoSQL has limits, it may struggle to maintain ACID (atomicity, consistency, isolation and durability) compliance that prime of problems such as inventory information not being simplified in real time on an eCommerce website.
Reasons for using NoSQL:
NoSQL is an important part of the new data stack supporting, i.e. big number of users, data, supply chains and so on. NoSQL is there when something becomes so big that it must become largely distributed. The bigness can be across to many different dimensions; it is not just limited to huge disk space.
In the general mind-set, it is the second most cited virtue of NoSQL. It is a bit difficult to exhausted hashing on a key and reading the value from the memory directly when invisibility is essential.
The whole range of new data types is supported by NoSQL and this is a main area of innovation in NoSQL. We have graph, advanced data structures, key-value, column-oriented, and document-oriented. One can easily store complex objects without a lot of mapping.
With Schemalessness, one can easily deal with schema migrations without any worry. Schemas are in a sense dynamic, as they are imposed by the application at run-time, so various parts of an application, can have a diverse view of the schema.
SQL and NoSQL databases perform the same thing but in different manners. It is possible to select one for your business and move to another later, however, it could cost much time and money later. SQL database seems to be more practical alternative – when the project introduces eCommerce facilities that need for robust transaction support.
