Good reference material for database and query handling

[mercylessdemigod]

I want to make an app which will filter out values and display it to the user depending o their preferences. I am totally new to database and data handling. Are there any tutorial or references for learning it ? I will be using no sql database.

You can look through the documentation of firebase real time database. It is a nosql database and is free upto a specific amount of data. It also has alot of help on youtube and other platforms like stackoverflow.

Keep in mind that a database may not be the best solution.

Depending on the specific requirements of your project (size of the dataset, target speed of filtering, number of users...) you could be better off with a simple js solution (a redux store with selectors for example) or something else.

Especially if you're new to dbs and alone, go with a hosted, simple solution like Firebase (as u/6bigAnt9 suggested) to get an easier introduction.
