Database help for adding/editing data.

[FireMan]

Hello, I need your help friends, if you can assist me I would appreciate it.. Consider multiple products, I can extract the prices of these products with a bot and write them into the database. However, let's say for product X, on 27.05.2019, the price was 50 TL, the bot I created will visit that product daily. Now, suppose on 28.05.2019, the price of product X became 60 TL, how can I add this new price without deleting the previous ones and display the newly added data on the screen? Additionally, how can I keep track of the history of product X in the database? Thank you
