What lessons should I look at to create a program that saves and load data?

Question

Am new to programming, I got the basics down and I learn all of C# materials and can make little programs. But I want to know how to create a program that will allow me to save data and load the data later on. So I can make a cashier kind of system where I can save and load data such as name and quantity and such. I know am aiming big 😂😂 but I want to learn something challenging and something new. So anyone got any lessons that I should be looking at?

Answer 1

well you would look into storing the data in some sort of database, specifically C# and SQL interactions
