Given the following case you are to answer the two questions on the following pages.
Bob’s Supply (BS) needs to keep track of the parts they have in their inventory. He wants to know the description of each part, the color of each part, how many of each item is in stock [QOH], and how much each part costs him. BS also needs to keep track of who supplies each part, the supplier’s name, contact person, and telephone number. We know that each part in inventory has only one supplier, but some suppliers supply multiple parts to BS. Bob wants each part and each supplier to have assigned an identifying number.
1. Identify the tables needed to design the database and the fields [attributes] needed for each table and the role or function that some attrIbutes take on.
2. Create the database design for this case below using an Entity-Relationship Diagram.
How can I Draw An ERD to show the relationships among EMPLOYEE, STORE, REGION, and SUPPLIER.
A REGION can contain many stores. A STORE is located in only one REGION. The relationship between STORE and REGION is M:1. (It is, of course, equally true that the relationship between REGION and STORE is 1:M.) . In summary, each store is located in a single region, but that each region can have many stores located in it. You will have to keep track of attributes Region name, states included in the region, and the regional director's information.
A STORE employs EMPLOYEE, This is a 1:M relationship because one store can employ many employees and each employee is employed by one store. You will need to track, store address, store phone number, store manager, store number
There is still another relationship, the additional relationship, expressed by EMPLOYEE manages STORE, is a 1:1 relationship, because each store is managed by one employee and an employee manages only one store.' You will…
Use the 20 year Global Warming Potential (GWP) values in the first Table to calculate an equivalent CO2 emission rate for worldwide greenhouse gas emissions as given in the second table. Assume that total CFCs are divided equally among the three compounds listed. What is the percentage contribution of actual CO2 emissions to the total equivalent CO2? What is the next most important greenhouse gas emission based on this analysis? How do these results compare to those using the 100-year GWP.

To test this, you decide to use a natural experiment in which a chain of gas stations ("Thrifty") suddenly closed. This closure occurred between June and October of 2012, and meant that gas stations that were previous close to a Thrifty station experienced less competition than before. On the other hand, those stations that were not close to a Thrifty station did not experience any change in competition. You decide to use a differences in differences design, in which gas stations located near a Thrifty station at the start of 2012 are the treatment group and those that were not located near a Thrifty at the start of 2012 are the control group. You look at how prices change before and after the exit of Thrifty. This is plotted in the below graph, where the solid line represents the average price of stations that were…arrow_forwardBob’s Supply (BS) needs to keep track of the parts they have in their inventory.

- Damon Davis was creating the Drano Plumbing Company's spreadsheet. He determined that the net income would be $50,000. When he tallied the columns on the Balance Sheet, the totals were as follows: debit, $400,000; and credit, $300,000. What was the most likely reason for this discrepancy? If this was not the case, how should he proceed to determine the source of the error?arrow_forwardYou have been retained by “Expressive Espresso” to help them decide where to buildtheir next Expressive Espresso coffee house. You are therefore interested in what affects the total number of sales per day. You thus look at fifty of the existing Expressive Espresso shops and gather information on each of them. You think average daily sales (in dollars) could be affected by location, so you decide to gather information on the zip code for each Expressive Espresso shop, but you also think that the number of cars that drive past each day along with the modal education (highest degree earned) of the people in the area are also important. You collect all the data and do your experiment. a. List all of the variables in the above experiment. Also list two potential categories for each variable. b. Now list the scales of measurement for the variables listed above. Write the name of the variable and thenstate its scale of measuremenarrow_forwardA transport company needs to model their activities. There are two types of employees in the company: drivers and operators. For drivers it is interesting to know the date of issue and type of the driving license, and the date of issue of the taxi driver’s certificate. For all employees it is interesting to know their personal number, address and the available phone numbers. The company owns a number of transport. For each transport, there is a need to know its type, year of manufacturing, and date of the last service. There are two types of transport commonly booked by the customers that are MPV and Saloon. There are also other types of transports that the company provides to the customers. The company wants to have a record of car trips. A transport may be picked on a street or ordered through an operator who assigns the order to a certain driver and a car. Departure and destination addresses together with times should also be recorded. Draw an enhanced entity relationship diagram in…arrow_forward

Your company operates in two different regions, each with its fleet of delivery trucks. The number of packages in each region can vary significantly, represented by two sorted lists: one for each region (nums1 and nums2). Your goal is to calculate the median delivery time it takes for packages to reach their destinations, considering both regions. This median time is crucial to ensure timely deliveries and customer satisfaction. The overall run time complexity should be O(log(m+n)), as you need an efficient method to calculate this median for effective logistics planning. In this logistics scenario, nums1 and nums2 represent the sorted lists of delivery times for each region. Just like in the original problem, you are tasked with finding the median efficiently, which is analogous to determining the median delivery time. Achieving this with O(log(m+n)) time complexity is…arrow_forward
- Read carefully the following case:Imagine that you work as an internal auditor for a company that owns several pharmacies throughout the city. Based on your audit plan, the first cycle to audit will be revenue. The first thing you do is document the processes related to receiving and processing the various sources of income. On your initial visit, you were able to observe the following:Once customers have the items to purchase, they head to the register, where a clerk processes the sale. The pharmacy has three cash registers, but does not have an employee who specifically works as a cashier at each one. This provides flexibility in the operation because, of the three employees that the business has, one can collect at any of the cashiers when available. By not having to leave a single person as a cashier, the cashier can focus on providing more direct customer service, refilling merchandise on the shelves, and even assisting in receiving or dispatching merchandise from the store.At the…arrow_forwardCan We use ARDL model for the following information?

Its business model calls for keeping costs as low as possible. The company has no automated method for keeping track of inventory at each store. Managers know approximately how many cases of a particular product the store is supposed to receive when a delivery truck arrives, but the stores lack technology for scanning the cases or verifying the item count inside the cases. Merchandise losses from theft or other mishaps have been rising and now represent over 3 percent of total sales.
