What does MDI stand for?

The term MDI stands for Multiple Document Interface. This is a type of graphical user interface that allows users to work with multiple documents within a single application window. In an MDI environment, a single parent window can contain multiple child windows, each representing a different document or task. This design facilitates easier management of multiple files, as they can be accessed and manipulated within the same application instance.

MDI is particularly beneficial in applications where users frequently need to switch between and manage several documents concurrently, such as in text editors, graphic design software, or integrated development environments (IDEs). This interface model enhances productivity by keeping the interface organized and consolidating resources.

Understanding MDI is crucial in software development as it relates to user interface design principles, which aim to improve usability and functionality for end-users.
