I have assignment on project design for software application. its a word document. i have to explain in detail about use cases and architecture. i am going to send you some images for examples;-

Architecture - This should include the architecture you plan on using. For example, if you plan on using a layered approach, include a diagram such as seen in figure 6.6 with general information about what will be included in each layer.

Use Cases - There should be a section that includes use cases for the software development project. There should be at least one use case for each requirement that you identified on the requirements analysis document for your software project.
