- 4. How does MySQL work? Built on the Client-Server Architecture, the model is specifically for the end-users to access resources from a centralized computer known as a server. The requests to the server are made through GUI (Graphical User Interface) in lieu of getting the desired output. The requests to the server are matched with the instructions similar to the client- server model. MYSQL server is the backbone behind the working of the MYSQL database. The server handles the entire set of database instructions, commands, and statements being a separate program.
