Scenario:
Jonny is appointed as an intern position, which might lead to a junior database architect role in TechTrend Corporation (TTC). Jonny is assigned to redesign two legacy tables related to "Suppliers," to be normalization compliant. The following business rules are provided.
Business Rules:
1. Suppliers can be local or national, thus can have multiple locations.
2. Any location can supply items to TechTrend.
3. Any location manager can have a separate pricing deal with TechTrend, based on production process specific to that location and localization efficiency.
4. Each location has a contact person assigned to TechTrend.
5. Traditionally, TechTrend dealt with a singular location, at the most two. With rapid growth in business, the TTC officials are finding better leverage possibilities to negotiate beneficial terms with suppliers in multiple locations.

Assume that you are a database specialist for Kulliyyah of Information and Communication Technology (KICT). You are required to create a conceptual data model for Abu Hurairah Club. The following are the data requirements gathered:
The Abu Hurairah Club has a few animal shelters. Each shelter is identified by an identification number and has an address, a phone number, and a set of days on which it is open. A shelter is managed by one employee.
An employee has an identification number, name, address, phone number, and a pay rate.
A volunteer has an identification number, name, address, phone number, and a meal allowance.
A person, who works at a shelter, is either an employee or a volunteer, but not both. A person may work at more than one shelter for some regular set of days each week.
An animal is housed at one shelter. Each animal has an identification number that is unique to its shelter, a name, a birth date, and a species.

- Create an Entity-Relationship Model for the Queen Anne Curiosity Shop The first assignment for the class project is to create an entity-relationship model of the Queen Anne Curiosity Shop database. This assignment requires you to apply the knowledge gained from study of chapter 4 of the textbook. You will create the entity-relationship model using the ERDPlus database modeling tool. The Queen Anne Curiosity Shop database contains the following tables: CUSTOMER (CustomerID, LastName, FirstName, Address, City, State, ZIP, Phone, EmailAddress) EMPLOYEE (EmployeeID, LastName, FirstName, Phone, EmailAddress) VENDOR (VendorID, CompanyName, ContactLastName, ContactFirstName, Address, City, State, ZIP, Phone, Fax, EmailAddress) ITEM (ItemID, ItemDescription, PurchaseDate, ItemCost, ItemPrice, VendorID) SALE (SaleID, CustomerID, EmployeeID, SaleDate, SubTotal, Tax, Total) SALE_ITEM (SaleID, SaleItemID, ItemID, ItemPrice) Note that the above table descriptions follow the textbook convention:…arrow_forwardProblem A: A retail chain of pharmacies, Prescriptions-R-X that sells prescription drugs has hired your team of data analyst to design its database. Here's the information that your team gathers after discussions with managers from Prescriptions-R-X: Patients are identified by an SSN, and their names, addresses, and ages must be recorded. Doctors are identified by an SSN. For each doctor, the name, specialty, and years of experience must be recorded. Each pharmaceutical company is identified by name and has a phone number. For each drug, the trade name and formula must be recorded. Each drug is sold by a given pharmaceutical company, and the trade name identifies a drug uniquely from among the products of that company.

It should contain an ID, Title, Year Released, Genre (e.g., sci-fi, comedy, thriller, etc.), Rating (e.g., G, PG, R, etc.), Format (e.g., VHS, DVD, MP3, etc.), a free-form Comments field, plus the main cast and crew members. Add the following entry plus at least two of your own: Title: Star Trek Year: 2009 Genre: Sci-Fi Rating: PG Format: DVD Director: J. J. Abrams Starring: Chris Pine (Capt.
