# Lab 2 ## Scenario Code&Code is a small company dedicated to Software Development. Their engineering team, to which you belong, is working on writing a Web Application as an MVP for a new customer. The code name for this App is “Loggy”, which is meant to offer functionality for a personal journal where users can log their daily activities through text, voice and video. The first step will be to write the main functionality, which is essentially a Microblogging System where all the posts are automatically annotated with voice, video or text. As an initial step, you must create the skeleton of the back-end service for performing the automatic closed captioning under these assumptions: - The closed captioning is performed through an external service (AWS or GCloud). - There should be an internal controller that: - Receives the recordings to be processed from a requester - Sends the recordings to the external service - Receives its response - Updates the recoding with the resulting…

Medical Unlimited Medical Unlimited (the brainchild of a group of young philanthropic medical professionals) is interested in setting up a mobile medical unit that provides free medical services for students. The mobile medical unit will require a patient record and scheduling application that will be used by the medical staff (doctors/nurses) and receptionists working there. The receptionists will use the system to capture new patient information when firsttime patients visit the doctor. Receptionists will also be responsible for scheduling all appointments. Nurses on the other hand will use the s ystem to keep track of the results of each visit including diagnosis, medications, prescription and treatment. Multiple medications may be prescribed during each visit. The nurses can also access the information to print out a history of patient visits. Th e doctors will primarily use the system to view patient history. The doctors may enter some patient treatment information and…
