Databases

What can an application manage without data? Well, nothing at all!
And that’s why a database is the most important part of any application as it is required to store and access the data. So a Full Stack Web Developer needs to know the divide between Relational and NoSQL databases to understand the situations in which each would be useful. They should also be familiar with databases of each type such as MySQL, MongoDB, etc. In addition to all this, knowledge of caching options such as Redis, Memcached, and Varnish would only be a plus!
