(Project: Emergency Response Class) The North American emergency response service, 9-1-1, connects callers to a local Public Service Answering Point (PSAP). Traditionally, the PSAP would ask the caller for identification information—including the callers address. Phone number and the nature of the emergency, then dispatch the appropriate emergency responders (such as the police, an ambulance or the fire department). Enhanced 9-1-1 (or E9-1-1) uses computers and
9-1-1, visit www.fcc.gov/pshs/services/911–services/welcome. html and people.howstuffworks.com/9–1–1–.htm.
An important part of creating a class is determining the class’s attributes (instance variables). For this class design exercise, research 9-1-1 services on the Internet. Then, design a class called Emergency that might be used in an object-oriented 9-1-1 emergency response system. List the attributes that an object of this class might use to represent the emergency. For example, the class might include information on who reported the emergency (including their phone number), the location of the emergency, the time of the report, the nature of the emergency, the type of response and the status of the response. The class attributes should completely describe the nature of the problem and what’s happening to resolve that problem.

The mechanic will inspect the vehicle and be paid for it. They will store the inspection result in the inspection record. Based on the record, the mechanics can repair the vehicle too if the customer wants and be paid for it. The owner can order parts to the vendor if there is any shortage in the inventory. The customer will pay bill for inspection and repair. Draw a Data Flow Diagram (Level 0 and 1) for the system.

The client's ultimate objective is to have an online software system that gives information about the movies that the client sells to customers online. The system gives information about movies and actors/actresses. That is, the system should be accessed online. Each movie is identified by title and year of release. A movie has a genre (drama, comedy, etc.), a running time, and one director. A movie is made at a movie studio and may have multiple producers (people in charge of the movie production). A movie studio has a unique name and address, and may make one or more movies. Producers are identified by name and date of birth and produce one or more movies. Directors are also identified by name and date of birth and direct one or more movies. Assume that directors don’t act or produce movies. Actors are identified by name and date of birth, and may appear in one or more movies. An actor who appears in a movie, has a role. There may…arrow_forwardFortune 500 Company: Walt Disney A. About the Organization: The first step is to describe the organization at which the IT problem(s) exist / could exist. Preferably, this should be an organization that you have previously worked at, or are currently working at. Otherwise, you can search for non-trivial IT-related problem(s) that major (i.e., Fortune 500) corporations have faced, and take that on as the problem(s) you are going to address in your case study writeup. In addition to a general description of the business, analyze the organization using (a) Porter’s Five Forces model, and (b) the Value Chain model (i.e., how does the organization create value) B. Problem Identification and Analysis The next step is to identify the specific IT-related problem(s) at the organization. You must clearly describe the problem(s) in detail, covering both their technical as well as social aspects. Identify the stakeholders involved, and how the problem impacted / could impact each stakeholder.…arrow_forward

- Programming language to use: Java / Python Assignment: You have a dictionary of symptoms. Some are top level symptoms (Abdominal pain, Chest Pain) and others are children connected to these parents by relationships. Example: 'Abdominal pain, right upper quadrant' is a child of 'Abdominal pain' via relation 'location', 'Abdominal pain, mild' is a child of 'Abdominal Pain' via relation 'severity'. Dictionary: Abdominal pain Abdominal pain, right upper quadrant Abdominal pain, right lower quadrant Abdominal pain, left upper quadrant Abdominal pain, right upper quadrant Abdominal pain, mild Abdominal pain, moderate Abdominal pain, severe Chest pain Chest pain, left side Chest pain, right side Chest pain, mild Chest pain, moderate Chest pain, severe Tasks: Create the symptoms tree and print it.
