Answer / neil
SDI can load only 1 document at a time,however it can have
multiple views in the same window using splitter windows
property.
example is a notepad in windows.
An MDI application has multiple child windows, each of
which corresponds to an individual document. Microsoft Word
is a good example of an MDI application.
Here also we can have splitter windows property, with same
view in diff. windows or diff. views in diff windows.

Answer / dheeraj mehrotra
MDI = "Multiple Document Interface"
SDI = "Single Document Interface"
MDI is when your application consist of an MDI parent-form
that contains all the other window/forms that the app
consists of.
SDI is stand-alone, ordinary windows/forms that exists
independently
of each other.

SDI:
 We can open only one document at a time, Ex: Notepad
 SDI App hold only 4 classes (
CView,CDoc,CFrameWnd,CWinApp)
 SDI App has CSingleDocTemplate and holds 3 classes
MDI
 We can open multiple docs simultaneously, example:
MS Word
 MDI holds 5 classes (CChildWnd<---
CMDIChildWnd,CDoc,Cview,CFrameWnd).
 MDI has CMultiDocTemplate and holds below classes.
CMultiDocTemplate* pDocTemplate;
pDocTemplate = new CMultiDocTemplate(
IDR_MDIAPPTYPE,
RUNTIME_CLASS(CMDIAPPDoc),
RUNTIME_CLASS(CChildFrame), // custom MDI
child frame
RUNTIME_CLASS(CMDIAPPView));
AddDocTemplate(pDocTemplate);

Answer / tabrez ajaz
MDI means "Multiple Document Interface" &
SDI means "Single Docoment Interface"
Differences between both interfaces:-
1:- MDI supports multiple views means multiple windows at
the same time on the display screen. But
SDI supports one application window at a time.
2:-MDI supports many interfaces means we can handle many
applications at a time acoording to users requirements.But
SDI supports one interface means you can handle only one
application at a time

of each other.
MDI:
We can open multiple docs simultaneously.
example:MS Word.
MDI holds 5 classes (CChildWnd<---
CMDIChildWnd,C Doc,C view,CFrameWnd).

Answer / shakuntala
The full answer is available in MSDN, but in a nutshell SDI or a single document interface is a window that can only handle one document at a time per window. An example of an SDI is Notepad (you can only edit one text file per Notepad window. If you want to edit two files, you need two Notepad windows).
An MDI or multiple document interface is a window that can handle more than one document at a time (usually by creating subwindows). An example of an MDI is Visual Studio. You can have multiple Cpp files open in the same Visual Studio window (you navigate through each CPP file by using the tabs, or the Window menu). Most (but not all) MDIs implement a tabbed style interface similar to Visual Studio to navigate between documents.
