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:

The company wants to ensure that any devices connecting to their servers are properly registered and approved by the Information Technology department. The business requirements are attached.
Given the attached business requirements, create the complete Crow’s Foot ERD containing all primary keys, foreign keys, and main attributes. Use specialization hierarchy if appropriate. This ERD is the initial database blueprint. Use the normalization procedures to remove any possible data redundancies. This process may produce additional entities. If additional entities are created, revise the ERD created in previous…
Cloud computing is becoming a prevalent practice among multinational organizations. However, security in the cloud remains a significant barrier to cloud adoption. Some argue that the cloud isn't ready to hold secret or private data yet. What do you think of this argument? Answers may be explained with the use of real-world examples.
