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”...

We discussed many qualities that a requirement statement should possess. Find the issues with the following requirements and reformulate them into better requirements.
R1: The system must process transactions with an average latency of 5 seconds. To achieve this performance average, the website will be hosted by a powerful web-hosting provider. The hosting server must be monitored 24 hours a day. The server bandwidth must be unlimited, and storage capacity must not be less than 50 GB.
R2: The system shall provide a separate dashboard for manager or sales agents and display the transaction information based on their roles. Dashboard would allow them to view the monthly sales reports.
R3: Usability: The product should be usable by customers with different backgrounds and education levels. Users should be able to accomplish their tasks easily. In order to increase usability, the application must provide a responsive design for different screen sizes.
R4 (Use case):
Title: User Views…
Ben & Jerry's has developed a microservice-oriented accounting application consisting of various utilities and database connections. However, they are encountering performance bottlenecks as some of their microservices receive a significant number of requests from other actors, such as different microservices or subsystems within the domain. This problem adversely affects the overall efficiency of the entire application. What specific technique, feature, or solution would you recommend for Ben & Jerry's to effectively address and handle this high level of stress on their microservices?

Identify architectural elements of the Multics design that leverage the security architecture concepts of (i) isolation/zones and (ii) interface restriction. Saltzer mentions “Secondary Storage Residues” as a vulnerability in the system. Their exploitation would be a violation of what security property? Identify a potential remedy to this vulnerability. The Multics designers briefly considered a “Trap Extension” to their Access Control scheme. Discuss the positive and negative aspects of this approach related to the secure design principles of 1. least privilege, 2. economy of mechanism, and 3. complete mediation.arrow_forward
- Read the case study entitled “Hudsonbanc Billing System Upgrade” below.Two regional banks with similar geographic territories merged to form HudsonBanc. Both bankshad credit card operations and operated billing systems that had been internally developed andupgraded over three decades. The systems performed similar functions, and both operatedprimarily in batch mode on mainframe computers. Merging the two billing systems was identifiedas a high-priority cost-saving measure. HudsonBanc initiated a project to investigate how tomerge the two billing systems. Upgrading either system was quickly ruled out because theexisting technology was considered old, and the costs of upgrading the system were estimatedto be too high. HudsonBanc decided that a new component-based, Web-oriented system shouldbe built or purchased. Management preferred the purchase option because it was assumed thata purchased system could be brought online more quickly and cheaply.
