Some of the models capture static aspects for the system and one will capture dynamic behavior for the system. In this project, you are required to draw an activity diagram showing the actions and events involved in depositing a check to a bank account using a mobile app. In particular, your paper should provide the following: A simple pseudo-code that captures the sequence of that process A detailed activity diagram that maps to your pseudo code you identified Make sure to specify clearly any assumptions you feel important to understand your logic I'm a bit lost on what to do and really just need an example of what this is asking and then suggestions on how to go about doing the assignment.arrow_forwardEvent-Driven Approach Write a program (in any programming language) to simulate Event-driven approach. inputs: Arrival Times, and Departure times for entities.

- Draw an activity diagram that models the following employee reimbursement process: Employees of a university have to follow a specific procedure to get reimbursed for travel they undertake on behalf of the university. First, in order to prepare a reimbursement request, they have to do the following activities at the same time: gather all of the receipts the university requires for reimbursement and complete the official reimbursement form. They then submit both the receipts and the form to their departmental secretary for checking purpose. If something on the form is incorrect, the secretary returns the form to the employee and ask for correction. If the form is correct, the employee is asked to review the reimbursement amounts, which are determined by an analysis of the reimbursement request. If the amount shown is not correct, the employee must indicate that this is the case. If the amount shown is correct, then the employee": responsibilities for reimbursement are complete.arrow_forwardAn abstract procedure has no body.arrow_forward
