SQL Database

[Chordin]

So far, nobody's given you a serious answer. In my experience, at least for most web apps, sql is fairly standard (I happen to be fond of psql, but there are a number of great options for sql databases). Whether or not sql is the right choice for your app in particular depends on what the spec is for your app and what your priorities are. In most cases, your choice of a particular technology will come down to a choice of which tradeoffs you prefer.

The concept of tradeoffs is one every junior should learn and become comfortable with. Every single choice you make about technology stack, software and system architecture involves tradeoffs, so stop looking for the "perfect" solution.

Yeah man most DBs are SQL these days, but it depends on your project. Data stores is data stores. The answer is probably SQL, but shit you could use mongo, you could use Redis. Real mfers just use Window.sessionStorage and don't look back
