Explanation of Solution
Crow’s Foot ER diagram for Global Unified Technology Sales (GUTS):
The following data model shows the solution for the given question.
Explanation:
- In the above data model, one department can contain many employees. The primary key of “Department” entity is “Dept_No” and “Employee” entity contains “Emp_No” as primary key.
- One employee uses more than one enabled services. so, the primary key and foreign key of this “Enabled” entity is “Service_No” and “Emp_No”.
- The “Service” entity is used by the “Enabled” entity. The primary key of the “Service” entity is “Service_No” and foreign key is “Server_No”...

Global Unified Technology Sales (GUTS) is moving toward a “bring your own device” (BYOD) model for employee computing. Employees can use traditional desktop computers in their offices. They can also use a variety of personal mobile computing devices such as tablets, smartphones, and laptops. The new computing model introduces some security risks that GUTS is attempting to address. The company wants to ensure that any devices connecting to their servers are properly registered and approved by the Information Technology department.
Create a complete ERD to support the business needs described below:
Every employee works for a department that has a department code, name,mail box number, and phone number. The smallest department currently has5 employees, and the largest department has 40 employees. This system willonly track in which department an employee is currently employed. Veryrarely, a new department can be created within the company. At such times,the department may exist…

- Smart Airport Passenger Processing System (SAPPS) will replace the human administered, ID control, Airport check-in and boarding-pass processes. The new airport will have faster process timing and better security with SAPPS. The passenger will not interact with any officer at this new airport. Once SAPPS installed, the passenger will walk through a passage surrounded by cameras, microphones and other remote readers to do “ID control, Airport check-in and boarding-pass process” all at the same time Each customer will be given and RFID bracelets when they enter to the airport. In the new airport, passenger will get a RFID bracelet at automated kiosk, this is an ATM type machine has face recognition cameras, finger-print reader and connection to DMV and IRS to authenticate the passenger and update the Airport database. This is the only step where passenger will stop and wait for the machine to put the RFID bracelet on his/her wrist. Then, passenger with RFID bracelet never stops until…arrow_forwardFacebook Data Move Project Facebook deals with various kinds of risks on a regular basis, and the risk of service interruption is high on the list. About five years ago, Facebook was involved in a multimillion-dollar effort to move a terabyte of data from a near-capacity data center to a then new higher-capacity data warehouse. The project was scheduled to be completed in 100 days with no provision for any schedule delays. In Facebook terms, a terabyte is equivalent to 250 billion “Likes” on Facebook. The project had two phases, i.e., building and outfitting the new data warehouse, and then moving data to the warehouse. The new data warehouse was designed so the servers could handle four times as much data as the current servers, and the processors and software were upgraded as well. As a result, the new data warehouse could hold eight times more data than the current data center, and it could also move and manage data more efficiently. To reduce the risks the project team took a…arrow_forwardRocky Ridge Enterprises uses desktops in a peer-to-peer network to share files and a printer. Management wants to implement a server-based IT system that uses Active Directory and provides more features and security than is currently available on the peer-to-peer network. They would also like to have some of this information available online to salespeople while on the road. Since they are unsure of their longer-term needs, they want to keep their hardware costs to a minimum.

They have recently expanded their premises, adding a new main office and a community hall. Recognizing your expertise as a CTU student specializing in network infrastructure and security, they've approached you to design and simulate a Local Area Network (LAN) that caters to their growing needs. They've emphasized the importance of a secure, efficient, and scalable network. Objective: Your task is to use Packet Tracer to design a simulated network that meets the center's requirements. The simulation should be as close to a real-world setup as possible. Requirements: 1. Main Office Setup • Computers: Set up three computers named Office PC1, Office PC2, and Reception PC. These are essential workstations where daily administrative tasks are performed. • Connectivity: Use copper straight-through cables to establish connections between…arrow_forward
