Explain different window management schemes.

Single-document interface:
- Description: It uses a single main window for one primary task or document.
- Example: Like having a single window for writing a document or viewing a folder.
- Use case: Suitable when you mainly focus on one thing at a time.
Multiple-document interface (MDI):
- Description: It allows you to work with multiple documents or views at the same time.
- Example: Imagine having several documents open in one application, like multiple tabs in a web browser.
- Use case: Useful when you need to compare or work on different things simultaneously.
Workbooks:
- Description: Organizes views like pages in a book, where each section is a tab within the main window.
- Example: Think of it like flipping through pages in a notebook, with each page representing different information.
- Use case: Helpful when you want to navigate between different sections of information easily.
Projects:
- Description: Similar to MDI but without visually containing child windows; instead, it uses icons representing objects.
- Example: Having a project window with icons, and clicking on an icon opens a separate window for that object.
- Use case: Useful when you want to keep different tasks or projects organized separately.
