The document summarizes the document-view architecture in Microsoft's Visual C++ programming. It discusses how the document-view architecture provides a framework for applications that manage disk-based data. The document stores the data and coordinates updating multiple views. The view displays the data and manages user interaction. Key classes in the architecture include the document, view, frame, and application classes. The document-view model separates the data and display, allowing multiple views of the same document like a spreadsheet and chart view.
