MDI vs. SDI: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 2, 2023
MDI (Multiple Document Interface) allows users to manage multiple documents within a single window, while SDI (Single Document Interface) provides a dedicated window for each document.

Key Differences

MDI, or Multiple Document Interface, allows an application to contain multiple sub-windows, each holding its own document, within a single main window, whereas SDI, Single Document Interface, ensures each document is contained within its own primary window, independent of others.

MDI applications present a frame or main window that contains and groups various child windows, each of which might host a separate document or view, while SDI applications spawn a unique window for each open document, with each window functioning independently.

Navigation in MDI tends to be centralized within the parent window, providing a unified location to manage and switch between documents, while SDI demands users to navigate through individual windows, typically utilizing the taskbar or a similar interface tool.

MDI can be considered advantageous in scenarios where comparing or quickly switching between different documents is vital, while SDI might be favored in applications where isolated, focused interaction with documents is paramount.

Some users might find MDI to be cluttered or convoluted when numerous documents are open due to the singular parental window, while SDI might be seen as disorganized when managing numerous documents since each document populates its own individual window.
