A pharmaceutical company produces customized medical equipment for one-time usage in hospital surgeries. The CEO decided to provide an online business-to-business order platform for hospitals through the Web after being approached by two major hospitals. In the first phase of the iterative development project for the order platform, a set of requirements have been completed. The requirements engineer needs the agreements of the stakeholders to hand the requirements over to the development team for implementation.
Validation is an iterative process. Therefore, the team is required to conduct another validation session after all the corrections (of the first validation) are made. However, if the team refuses to perform the second requirements validation due to time constraints, what do you think the possible risks that the team might face?
Let’s take a look at the following context diagram of payroll system.
2. Design level-2 DFD based on following scenario.
Calculate pay process is decomposed in two processes, compute net pay and prepare payroll. Compute net pay process take valid payroll data and exemption data from withholding datastore and generate Net pay and deduction which is saved to employee datastore and also sends to prepare payroll process. Finally prepare payroll process saves posting information to payroll journal datastore and send paychecks to Employees.

- A new sales ordering system needs a relational database that contains a customer table, a product inventory table, and an order table. Use a word-processing, graphics, or spread-sheet program to draw an entity-relationship diagram showing the relationships among these entities. Next, design each of these tables showing the keys and attributes to be included in each table. Include five sample records for each table.arrow_forward1. UPS company always keep up to date for all their processing information and also the current location details of each shipped item. To ensure the information is always up to date due to the complexity of data, UPS relies on a centralized information system that stores this huge amount of data. Shipped items are the main component of the UPS product tracking information system. Particularly, shipped items can be characterized by the item number (unique), weight, dimensions, insurance amount, destination and also final delivery date. Shipped items are received into the UPS system at a single retail center. Retail centers can be characterized by their type, uniqueID and address. Shipped items make their way to their destination via one or more standard UPS transportation events/channels (i.e., flights, truck deliveries). These transportation events/channels are characterized using a unique scheduleNumber, a type (e.g, flight, truck) and the deliveryRoute. a.

- Draw a Diagram 0 based on the given situation below. You will need to identify external entities, processes, and data stores before drawing the diagrams. (Manually draw and scan the diagram) Fresh-Mart Grocery is a regional grocery chain that is developing an information system to monitor inventory levels, product sales, and merchandise turnover. As products are sold in stores, they need to be replaced by shipments from the distribution centers. The IT manager wants you to document a process called BALANCE that determines whether extra product inventory is needed in a particular store. The BALANCE process is to be used in a just-in- time inventory system that automatically orders products and routes them to various stores for sale. A store manager can override the automatic BALANCE process if he or she so desires to get more product into a store.arrow_forwardQuestion System: Sales Accounts Management System Reciprocal Sales Corporation is a global sales company that works with leading Fortune 500 corporations.

Research on the Web to identify what you believe to be the set (version) of steps that you'd use to complete a Data Science project. You should find versions with 5, 7, 9, 11, 12, or more steps. If you choose a particular set of steps, cite your source and explain why you would use that approach. If you wish, you can develop your own approach, drawing on the research, if you think there may be a better way. As you get deeper into Data Science, in subsequent courses, you should learn the validity of your approach. List the steps of your approach, cite its source, and provide an explanation of why this particular approach would work best for you.arrow_forward
