a) How a software development process model can be used as a web development process model. Specify the constraints on using a software process model for web applications and what needs a process model should cater to adapt itself to diverse web applications. b) Clarify system modeling. Outline the dimensions of system modeling for web applications with help of examples. Perform the four major modeling activities used for each task by using a case study to build a simple website for a To-Do App. (You can use any other web app for modeling, but all the modeling activities should be carried out for a single application)
