How do we store pictures or any other files in the database?

Can we store files as well in the database or do we need NoSql database for that?

Well, a VARCHAR is a native SQL data type that stores a variable-length sequence of characters with the last two bytes giving its size. I.E, "JEN" would be stored using 5 bytes, one for each character and 2 for the length. VARCHAR is usually preferable over the CHAR type unless the data is all the same size and short in length. So VARCHAR(250), 250 is the maximum number of characters it will store in a single entry. What is String (500)? String is NOT part of the SQL syntax but is a function used by Sequelize ORM to handle the VARCHAR data type. If you were to write just Sequelize.STRING it will create a VARCHAR(255) (if no size given).

So STRING (500) would create a VARCHAR (500) in the database. Here are some of the common sequelize data types, and here is the Sequelize documentation covering the String type. Hope that helps :grinning:

Although you can store images, videos, and the like directly in the database using the "Blob" and "varbinary" fields, it is not recommended. Usually, the image or file will get stored on the server in a resources folder and you will just store the link or pointer to it on the database itself.
