DataBase

You can call me outdated but I have never used a NoSQL database before. They both do the same thing. To store data. But they do it differently. SQL databases stores data in database systems hosted on your server. NoSQL databases are more portable as they store data in binary json or other formats. If SQL is mainframe, NoSQL is Azure! Absurd comparison but hope you get it 😉

Just as XML and json are different, sql and nosql(mongoDB) are different. You can use both databases as you want. But I recommend for you sql. Cause sql is simple
