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.
6. The DB administrator has specifically requested Johnny…

- Problem 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. If a pharmaceutical company is deleted, you need not keep track of its products any longer. Each pharmacy has a name, address, and phone number. Every patient has a primary physician.

- Consider the following schema: Suppliers(sid: integer, sname: string, address: string)Parts(pid: integer, pname: string, color: string)Catalog(sid: integer, pid: integer, cost: real) The key fields are underlined, and the domain of each field is listed after the field name. Therefore sid is the key for Suppliers, pid is the key for Parts, and sid and pid together form the key for Catalog. The Catalog relation lists the prices charged for parts by Suppliers. Write the following queries in relational algebra, tuple relational calculus, and domain relational calculus: 1. Find the names of suppliers who supply some red part.2. Find the sids of suppliers who supply some red or green part.4. Find the sids of suppliers who supply some red part and some green part.5. Find the sids of suppliers who supply every part.

While the clerk can see salary information for any statistical analysis (e.g. average salary computation), he has no idea which employee the salary is for. The role 'Administrator' is granted rights on all three tables; using the confidentialId in the employeeMap table, she has access to salary data for individual employees too. A SQL query that the administrator can use to access all employee fields is: select e.id, e.name, e.address, es.salary from employee e inner join employeeMap m on e.id = m.id inner join empSalary s on m.confidentialId = s.confidentialId; Can you draw a database schema?arrow_forwardQuestion 6 V Saved Problem 4-7 will use the same database.
