SQL can be extended, and is versatile and time validated, which can solve problems from fast write-driven transmission to scanning intensive in-depth analysis.4. SQL is an orthogonal form of data rendering and storage, and some SQL systems support JSON and other structured object formats, with better performance and more functionality than NoSQL.Although N
