The user
The user data is a simple structure that is used to log in to a system. It has an e-mail address, a password, and a name.
Do not delete the user data and physically manage it with a flag. It is connected to other data structures with joint ownership, recording the date and time when it was created along with the updated date and time.
When we design a table with a model of MySQL, it looks similar to the following table. After having carried out MD5, we perform SHA1. Then, we will have 40 characters and can store the password.
