Given the following business rules that describe a bookstore operation and the cardinalities involved, draw a basic crows foot erd that includes cardinalities and visually describes the basic bookstore operational relationships between the business entities.

Given the following business rules that describe a bookstore operation and the cardinalities involved, draw a basic Crows Foot ERD that includes cardinalities and visually describes the basic bookstore operational relationships between the business entities.
One student places one-to-many orders.
One order lists one-to-many order-items (books).
One book can be listed in any order items.
A course requires one or more books.
Remember that entities are identified by the nouns in the business rules. Each noun will become an entity. I would highly recommend you watch the video Entity Relationship Modeling in our Weekly Assigned Readings and Videos.Entity Relationship Modeling – YouTube You can also create your ERD using pen and paper, so you don’t need to use a modeling tool. If you do build your ERD using pen and paper make sure your entity’s names and cardinality symbols are easy to read and recognize.
Here is a basic example of a business rule and how this business rule is represented in a Crows Feet Diagram:
(Nieland, 2021)
One customer can have many customer requirements and one customer requirement belongs to only one customer.

It is much faster to read from and write to than other kinds of storage, such as a hard disk drive (hdd), solid-state drive (ssd) or optical drive.

What is RAM?
RAM (Random Access Memory) is the hardware in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device’s processor. RAM is the main memory in a computer. It is much faster to read from and write to than other kinds of storage, such as a hard disk drive (HDD), solid-state drive (SSD) or optical drive.
Random Access Memory is volatile. That means data is retained in RAM as long as the computer is on, but it is lost when the computer is turned off. When the computer is rebooted, the OS and other files are reloaded into RAM, usually from an HDD or SSD.
Function of RAM
Because of its volatility, RAM can’t store permanent data. RAM can be compared to a person’s short-term memory, and a hard disk drive to a person’s long-term memory. Short-term memory is focused on immediate work, but it can only keep a limited number of facts in view at any one time. When a person’s short-term memory fills up, it can be refreshed with facts stored in the brain’s long-term memory.
A computer also works this way. If RAM fills up, the computer’s processor must repeatedly go to the hard disk to overlay the old data in RAM with new data. This process slows the computer’s operation. If you want more details, so support me.

This week you will be creating a Work Breakdown Structure (WBS) for purchasing a car. Think of all the tasks that you perform when you purchase a car. Include any research, decisions, or financial issues that relate to the purchase. Create a WBS that shows all the tasks, their estimated duration, and any predecessor tasks. Your WBS should be similar to the WBS in our assigned readings – Figure 3-27 on page 101 and Figure 3-8 on page 81.
Your WBS needs to include the following four columns:
1. Task Number
2. Description
3. Duration
4. Predecessor Task
You need to include a minimum of eight tasks in your WBS. Each row in your WBS needs to be complete, logical, and descriptive.

Learning Goal: I’m working on a computer systems and need to help me learn.Network Design for ReliabilityThere is an increasing reliance on network connectivity to support critical business functions. In this information age, the majority of business transactions are now conducted online. This dynamic has created an expectation of high-availability from a business perspective. The time when a business may have been able to get by with an entire day of downtime is no longer acceptable. Nowadays, a 2-hour outage is considered too long. Many organizations are running 24/7 operations and requiring a 99.9% uptime that is roughly 8 hours of downtime per year. A 99.999% up-time in comparison is approximately 5 minutes of downtime a year. One of the drives of 24/7 operations is the increase in mobile computing and VPN access. By providing employees with the ability to access corporate resources from their home or on their phone have created more reliance and demand for network connectivity.Network reliability and availability are often used interchangeably but represent two different things. Reliability represents the probability that the system is operational within a time period without any failure, while availability represents the probability that the system will be operational when called upon in that instance of time (Mesbahi et al., 2018). High network reliability and availability comes with a cost. The greater the uptime, the greater the cost. When designing for reliability, it’s important to weigh the business needs against the cost. It is also critical to identify points of failure in your network architecture. This includes matters such as hardware, connectivity, power, human factor, and natural disasters. Once the critical components have been identified, you can then add redundancy to address single points of failure. Human factors can be mitigated through proper controls and processes.The cloud offers a high percentage of uptime and reliability though it is still immune to outages. Research shows that Cloud service failures have resulted in approximately $285 million in losses (Mesbahi et al., 2018). This week, you uncover different strategies for implementing reliability to support 99.999% up-time in a 375-day per year operation. You will develop a presentation to support your design recommendations.ReferencesMohammad Reza Mesbahi, Amir Masoud Rahmani, & Mehdi Hosseinzadeh. (2018). Reliability and high availability in cloud computing environments: a reference roadmap. Human-Centric Computing and Information Sciences, 8(1), 1–31. https://doi-org.proxy1.ncu.edu/10.1186/s13673-018-…Assignment: Design for Reliability Due April 17 at 11:59 PMThe CIO has reviewed the high-level design (Week 3 Assignment) and has requested that you add redundancies to ensure the network is available 99.999% of the time (365 days per year operation). The issues you need to account for are power failure, inclement weather conditions, single cable or conduit failure, Internet connectivity, networking hardware, and server failures.For this assignment, you will prepare a presentation for the CIO that covers the changes to the design you have made to support the desired network reliability. Your presentation should include the following:High-level network design with added redundancy that supports 99.999% uptime
Estimation of the maximum hours of downtime that the company can expect in a given year to support its 99.999% uptime requirement
Risk mitigation plan that takes into consideration these factors:Power failure
Inclement weather conditions
Single cable or conduit failure
Internet connectivity
Hardware failure (network device, server)
Use the speaker notes to provide what you would say for each slide, then make a video recording of the presentation. Use citations to support the best practices that you have used in your design.Length: 12-15 slides, not including title and reference listSpeaker Notes Length: 200-350 wordsReferences: Include a minimum of 5 scholarly resources.The completed assignment should address all of the assignment requirements, exhibit evidence of concept knowledge, and demonstrate thoughtful consideration of the content presented in the course.
