Question

I am working on web application and I have to submit it's high level design/architecture diagram.Can anybody tell me what exactly architecture diagram is?

PS: I have to draw class diagram seperately.

Answer 1

Architecture diagrams is about technology going to be used, and communication between them. Like, I have web application, I am doing this diagram.

1. Client(Android/IOS(java/objective C, or some framework like, trigger io or titanium)).
2. Client(Browser app(some technologies, like css3, lesscss, jquery, or angular js)
3. Web server(we have 2 servers, for example front-end server like ngnix, and back-end server like node.js or netty)
4. Database server (we use 2 databases for example, mysql and couch db) I also write for which reason what you are using.

Then you free to draw dependency between this things, to explain communication and understanding of stack being used for your application
