QUESTION: The recent Movement Control Order imposed due to the Covid-19 pandemic has affected most small businesses that sell food from home or roadsides. As the head of software development company, you are tasked to propose and develop a new online market platform to allow these small businesses to manage their sales and marketing through this platform. Sellers can register their businesses either through the web- based or mobile app platform. A registered seller will be provided with a virtual stall and the seller must upload all the necessary information for their potential customers. This information should be updated from time to time by the seller when needed. Due to limited funding and resources, the owner of this online market platform will not have its own riders to handle the delivery of the items bought. The system will leverage on existing delivery service systems such as Lalamove, MrSpeedy, and GrabExpress. When a buy ordered an item, the riders of any of these can accept to deliver the order. The delivery charges will be channeled to the companies that these riders are attached to. Buyers that wish to use this platform are required to register first and they will be provided with some features such as view product descriptions, inquiry chatting, shopping cart, payment, and other features that might be useful to the buyers. All payments are to be handled by the platform payment gateway provided by a third-party company. The payment platform allows buyers to pay using credit cards, debit cards, online banking payment, and some local e-wallet providers. Payment to sellers will be done thorough the same payment gateway after a small amount of commission is deducted from the sales. The online market platform will be managed by a team of staff for regular maintenance and monitoring work such as data back-up, termination of sellers, etc. The managers as well as owners of the platform would like to have executive reports such as dashboard information, sales reports, financial reports, etc. that are relevant to their needs. All stakeholders of the above platform should have their own requirements and expectations which may include security issues, user-friendliness, usage capacity, etc. As the head developer of this system, you will have you team to collect, and analyze these requirements. Based on the above case study, you are required to: Develop the Use Case diagram along with the required details. (20 marks) Develop the Class diagram along with the required details (including the multiplicities) (20 marks)
