1. Draw a use case diagram for an ATM machine with the following functionality. A customer's interaction with the system involves logging in, making withdrawal requests, deposit requests, and balance inquiry requests. If the customer logs in, there is a possibility (although rare) that the system will confiscate the card (for example, if the login is incorrect or if the bank determines that the customer's balance is significantly under zero). Card confiscation involves triggering an alert, which will be received by the branch manager of the bank. If the customer does a balance inquiry, this of course causes the system to check the balance. Checking the balance is also done when the customer requests a withdrawal, since the system must verify that enough money is in his account. In principle, checking the balance is a function that may be performed to support many use cases throughout the system.

Q: Develop a Swim-lane diagram for given scenario. The BRT service requires a system which will enable a passenger to buy ticket using an ATM like machine called as Ticket vending machine. Activity is started by Commuter / passenger who needs to buy a ticket. Ticket vending machine will request trip information from Commuter. This information will include number and type of tickets, e.g. whether it is a monthly pass, one way or round ticket, route number, destination or zone number, etc. Based on the provided trip info ticket vending machine will calculate payment due and request payment options. Those options include payment by cash, or by credit or debit card. If payment by card was selected by Commuter, another actor, Bank will participate in the activity by authorizing the payment. After payment is complete, ticket is dispensed to the Commuter. Cash payment might result in some change due, so the change is dispensed to the Commuter in this case. Ticket vending machine will show…
Course Title: Object Oriented Analysis and Design Question : There is a utility company which provides waste management services to citizens. It has a CRM system, billing system, messaging system and mapping (GIS) system. When a customer is created in the CRM system, the billing, messaging, and GIS systems need a copy of customer data to perform follow-up tasks and automation. For instance—the billing system will create a billing account for the customer, the messaging system will send a welcome message with customer account details on preferred communication channel and the GIS system will update the customer’s address in the database for mapping purposes. After completion of one billing cycle the billing dept. sends a copy of the bill in a pdf format on the customer email address and the bill amount is directly debited from the customer’s bank account. Draw an appropriate Activity diagram . (Note): Forks and joins have the same notation: either a horizontal or vertical bar (the…

Let us consider the following process performed by an IT helpdesk that handles requests from clients. The clients are employees of a company. There are about 500 employees in total. A request may be an IT-related problem that a client has, or an access request (e.g. requesting rights to access a system). Requests need to be handled according to their type and their priority. There are three priority levels: “critical”, “urgent” or “normal”. The current process works as follows. A client calls the help desk or sends an e-mail in order to make a request. The help desk is staffed with five “Level-1” support staff who, typically, are junior people with less than 12 months experience, but are capable of resolving known problems and simple requests. The hourly cost of a Level-1 staff member is € 40. When the Level-1 employee does not know the resolution to a request, the request is for- warded to a more experienced “Level-2” support staff. There are three Level-2 staff mem- bers and their…

Given the requirements that have been collected from the following end-users, draw a use-case diagram for them explaining all the necessary details. In this system, the subscriber enters his subscription data in order to log in to the website activities. If this data is correct, notifications, Messages, and Friend requests will be downloaded separately and simultaneously. It then displays friends' notifications, subscriptions, and updates on the subscriber's wall. A subscriber can comment, like, or post a specific piece of news. In the comment industry, the subscriber can upload an image or link to a website in addition to the ability to add his personal comment on it. The process of publishing a specific news has the same characteristics as placing a comment on a news in terms of possible events with the ability to upload a video clip. After that, the chat messaging wall is prepared, then it is necessary to ask the subscriber whether he wants to appear publicly or secretly to the…

Draw the Sequence diagram and Activity diagram for the following scenarios:The system should supports chain of hotels. A hotel contains two categories of rooms: executive and normal, both AC and non-AC. The customers of executive rooms can avail extra facilities like games, swimming, food service in rooms, etc. The booking is possible by internet or by phone. If the booking is through phone, process is done by receptionist, and if booking is done through internet the process is carried out by customer through hotel website. Depending on the number of days customer stays, appropriate bill is generated. The bill also contains amount for transport, food and other facilities enjoyed by the customer along with necessary taxes. The manager should be able to generate reports like list of customers staying in the hotel, list of rooms empty, monthly/yearly income,etc.
Scenario: Emporia Burgers is conducting the system analysis of a food ordering system. The objective o the analysis is to find what they should seek in a system that allows them to take orders online, at the store, or over the phone. These orders can be paid by cash, debit, or credit card. The system must also allow the restaurant manager to generate reports that can track the costs of goods sold, sales revenue, and inventory on hand. Finally, the system also creates work orders used by the kitchen personnel to prepare the customers' food orders and update the inventory on-hand. Generate a business process model for the scenario described
Many of Hoosier Burger’s customers work in the downtown area, so Bob and Thelma think a noon delivery service will offer additional convenience to their customers. Until a new system is implemented, the delivery service will be operated manually. Bob envisions the delivery system operating as follows. When a customer calls and places a delivery order, a Hoosier Burger employee records the order on a multiform order ticket. The employee captures such details as customer name, business or home address, phone number, order placement time, items ordered, and amount of sale. The multiform document is sent to the kitchen, where it is separated when the order is ready for delivery. Two copies accompany the order; a third copy is placed in a reconciliation box. When the order is prepared, the delivery person delivers the order to the customer, removes one order ticket from the food bag, collects payment for the order, and returns it to Hoosier Burger. Upon arriving at Hoosier Burger, the…
