Docker makes things much easier for programmers, when trying to create, deploy and run applications by using containers.
SQL databases are primarily called relational database. Whereas, NoSQL databases are primarily called the non-relational database. Whenever you want to create an application where there will be a relationship between the tables, like one-to-many or many-to-many or one-to-one, then you can go with the SQL database. On the other hand, if the tables do not have any relations then you can go with the NoSQL database choice.
