BKJIA: the majority of databases are composed of two completely different parts: the place where data is stored at the backend) and a user interface for connecting data components at the front end ). This architecture separates the user interface from the data layer. In this way, a third party can create its own application to interact with the database.
In this article, I will introduce some of the most commonly used MySQL GUI tools.
