DBMS > Inroduction > What is user Interface (UI)?

User Interface (UI) is the point of human-computer interaction and communication in a device. This can include display screens, keyboards, a mouse and the appearance of a desktop. It is also the way through which a user interacts with an application or a website.

The user interface includes languages, menus, and other facilities by which users interact with various system components.

 

In a databse-backed application, common mechanism for accessing the database is using application programs. An application program must consists of two key components:

• Graphical User Interface (GUI): to accept the users’ request (e.g., to input, delete, or modify data)
• Display: provide a mechanism for displaying the data retrieved from the database.

 

Client : The machine that runs by the user and send request to the server.

Database Server: The machine the runs the DBMS and contains the database. It receives request that sent from the client.
