1. 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 tiny manufacturing firm is growing its operations throughout the nation by building various locations. At the moment, all databases are handled by individual staff using Microsoft Excel or, on occasion, Microsoft Access. The firm is contemplating upgrading to a central database management system composed of many modules for the purpose of managing production, inventories, workers, and accounting. You have been engaged to create a feasibility study as the first part of the SDLC cycle, which will include suggestions on the economic, operational, and technical elements of the current project.
Windsor, a small city with a population of 50,000, recently purchased several buses and hired drivers to serve multiple routes in Windsor and neighboring areas. As the city's IT Manager, we have been tasked to set up an information system and database to manage the scheduling of buses and drivers that can be easily expanded as the city grows. We directed your team to follow best practices to develop a normalized database to manage the scheduling of drivers and buses that is simple, flexible, and non-redundant.
For this scenario above, assume that drivers can be assigned to different buses, and multiple buses will run on multiple routes. We may also assume the bus service is free, so no ticket purchases are required.
Hint: Build an ERD and decompose a many-to-many relationship into one-to-many relationships using an associative entity to link the entities. Assume a many-to-many (M:N) relationship between drivers and buses. Thus, a driver can drive many buses and a bus can be driven by…

- 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_forwardThe processes used to complete a data science project vary in their number of steps and functions, but in the end, the objectives and outcomes are similar. 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_forwardWindsor, a small city with a population of 50,000, recently purchased several buses and hired drivers to serve multiple routes in Windsor and neighboring areas.

Using DFDs, a data dictionary, and process descriptions, systems analysts Lisa Nuevo and Bill Goodman are developing the logical model of Tip Top's billing and records system. While developing the system's logical architecture, Lisa had the idea that the data forms that Tip Top uses to collect application data may need some changes. Was the problem with the forms' physical implementation the topic of improvement? If Lisa thinks about how something will be done rather than just what will be done, is she getting off track?arrow_forwardITEM_ID DESCRIPTION ON_HAND CATEGORY LOCATION PRICE AD72 Dog Feeding Station 12 DOG 79.99 BC33 Feathers Bird Cage (12x24x18) 10 BRD B 79.99 CA75 Enclosed Cat Litter Station 15 CAT 39.99 DT12 Dog Toy Gift Set 27 DOG 39.99 FM23 Fly Mask with Ears 41 HOR 24.95 FS39 Folding Saddle Stand 12 HOR 39.99 FS42 Aquarium (55 Gallon) FSH A 124.99 KH81 Wild Bird Food (25 lb) 24 BRD 19.99 LD14 Locking Small Dog Door 14 DOG A 49.99 LP73 Large Pet Carrier 23 DOG B. 59.99 B.arrow_forward
