I need help converting these entities into SQL Tables. Strong Entity (9)customer(customerID, nameF, nameM, nameL, street, city, state, email)customer_phn(customerID->, phone, type)product(productID, brand, device type, customerID->)tech_parts(partID, part_number, name, brand, price, modification if needed)employee(employeeID, nameF, nameM, nameL, street, city, state, email)employee_phn(employeeID->, phone, type)supplier(supplierID, name)supplier_phn(supplierID->, phone, type)refurbished_item(refurbishedID, item_source, brand, device_type, price, customerID->,employeeID->) Weak Entity (2)problem_sheet(date open, cost estimate, expected completion date, type of problem, final cost, date close, payment type, productID->, employeeID->, partID->) details(date, amount, partID->, supplierID->, customerID->)

Consider the following relational data model. Employee (empid, ename, address, title, headid) Works (Empid,Deptid,joindate) Department (Deptid, dname, block) Payment (title, salary) A) Write relational algebra for Display the employee name and department name of each employee. Display the employee who works as senior lecturer and belongs to BEI or BCT department. Display the employee name with corresponding department head.   B) Write sql query for Creating the above relations; including appropriate versions of all primary and foreign key constraints Find the employee name and address whose address name ends with substring ‘pur’. Update the salary of senior lecturer by 25%.(Solve  A - 1,2,3 only)

Consider the following Relational Schema: Employee (employee_name, street, city) Works (employee_name, company_name, salary) Company (company_name, city) Manages (employee_name, manager_name)   Write the SQL statements for the following querries: 1. List the employee names for all the employees not working for First Bank Corporation. 2. List the employee names with the salary greater that all the salaries from the Small Bank Corporation.

Using SQL data definition language, write the SQL statements to create each of the following relations. i. customer(cust id, lname, fname, initial, area code, phone, balance)ii. product(prod id, vendor id, description, expiry date, quantity, reorder level, price, discount)iii. vendor(vendor id, name, contact, area code, phone, state)iv. invoice(inv number, cust id, date, subtotal, tax, grand total)Note: Use primary key, foreign key and not null constraints where necessary.

thank you for the tips! but for demonstration can you break down this sql query to help me understand better what u mean in a practical sense?  Person (SSN, Name, Surname, DateOfBirth, Gender) SerologicalTest (CodT, CommercialName, Brand, Reliability) Building(CodB, City, Province Region, MaxCapacity) UndergoTest (SSN, CodT, Date, CodB, Outcome)    Considering only the buildings located in the Piedmont region (Region = “Piedmont”), find the dates of June 2020 at which the overall number of tests made in that building is maximal.     please keep in mind that im a beginner but also please explain everything rigorously i really have to understand the thought process before 4 days so i can at least solve questions of this level. its just relational tables nothing more for the exam for now.

Consider the following relational schema that consists of five tables. Primary keys are (BOLD and Italicized). Attributes with the same names in different tables are foreign keys. The address and name attributes are just one column each.   Person (driver_id, LastName, FirstName, EmailAddress, license, dateOfBirth) Car (license, model_id, color, report_num, trim) Accident (report_num, date, location) Model(model_id, description, year) PersonInsuranceCompany(driver_id, insurance_company_id, policy_issue_date) InsuranceCompany(insurance_company_id, name, EmailAddress)   3.1) Draw the corresponding ERD.  Draw eligibly!!!     Identify all relationships in the ERD that you created in part 3.1. For each relationship, identify the relationship connectivity (cardinality) and write a business rule to describe the relationship.

Simplify the following query (WHERE clause), expressed in SQL, on the example database above: SELECT ENAME, PNAME FROM EMP, ASG, PROJ WHERE (DUR > 12 OR RESP = "Analyst") AND EMP.ENO = ASG.ENO AND (TITLE = "Elect. Eng." OR ASG.PNO < "P3") AND (DUR > 12 OR RESP NOT= "Analyst") AND ASG.PNO = PROJ.PNO

Consider the database for a company named WPC that contains data about company employees, department, projects, company assets and other aspects of company operations. For the following questions, two tables will be considered as provided below: DEPARTMENT(DepartmentName, BudgetCode, OfficeNumber, Phone) EMPLOYEE (EmployeeNumber, FirstName, LastName, Department, Phone, Email) Department table: Employee table: Create SQL queries Display all of the data from both tables for production department. How many employees belong to either information systems or legal department?

Convert the diagram into a set of relational tables. The tables must be in 3NF. All referential integrity and functional dependencies must be indicated accurately in EITHER of the following 2 ways:  Draw lines for referential integrity and for functional dependencies as belows. 1. Show referential integrity as follows:    Supplier(S#, Sname, City, Status); Part(P#, Pname, Color, Weight, City); SP(S#, P#, QTY) Foreign key (S#) References Supplier, Foreign key (P#) References Part;  2. Show functional dependencies as follows: B → C CD → E

Subject - Fundamentals to Database Question 5 Based on the Table 5 and Table 6, write the SQL statement for the following cases in (5a), (5b), (5c), (5d) and (5e).
