Visual Programming
1. Discuss the comparison of single document interface and multiple document interfaces.
2. Write the advantages. And disadvantages of multi document interface
3. Write the application examples of multi document interface.
6. Explain SDI and MDI applications in detail.
9. Highlight the features of COM
Q1. Answer
MDI (Multiple Document Interface) and SDI (Single Document Interface) are different interface designs meant to handle documents within a single application. MDI allows an application to contain child windows per document, while SDI enforces one document per window.
Neither approach has much effect on performance or stability: despite the intuition of two SDI applications as being separate entities, they are very often still implemented as a single process. Similarly, an MDI interface can be implemented as multiple processes (Google Chrome being a prime example).
It's also worth noting that tabbed interfaces, although matching the description of MDI, often don't show multiple documents at the same time in the same window, and universally support multiple top-level windows as well.
