A hospital would like to set up a database recording which registered nurse looked after whichpatient etc. Each registered nurse has a unique nurse ID, and each patient has a unique patient ID,and the following attributes are found for nurses, and patients in the first round of design:NURSE: nurselD, suname, first name, birthdate, dept-code, sex, salary-levelPATIENT: patientlD, surname, first name, birthdate, wardlD, sex, admission_date, discharge_dateA recent duty list shows the patients that were cared by each nurse in past 2 months, see below forsome samples: nurselDpatientIDN0140000P123, P234, P883, P678N0172222P234, P334, P222, P883N0182222P243, P123, P883, P888N0163333P111, P123NO164444P222, P234You are responsible to help design this database for the hospital.a) What relationship (one-to-one, one-to-many, many-to-many) exists between NURSE andPATIENT? Explain your answer or draw an entity relationship diagram.b) How many tables would be needed to implement the relationship as indicated in (a)? List outthe attributes in each table, indicating which field(s) form the primary key, and which field isthe foreign key (if foreign key exists).

An insurance company needs to store their salespeople’s information who are selling their insurance policies. They already have a database with multiple tables, one of the tables (Salesperson) stores information about each salesperson along with the bonus percent they receive, based on the city where the insurance is sold. The table has the following fields: Salesperson(spID, spName, spBirthDate,spCitySelling, bonusPercent) spID: Unique identification number of the salesperson. spName: Full name of the salesperson. spBirthDate: Birthdate of the salesperson. spCitySelling: The city in which the salesperson is selling the insurance. bonusPercent: The bonus percent received by the salesperson based on the city in which he/she sells the insurance. Each salesperson can sell the insurance in just one city. However, for a city, there can be more than one salesperson appointed. Also, the bonus percent is fixed for each city.

Each publisher has a unique name; a mailing address and telephone number are also kept on eachpublisher. A publisher publishes one or more books; a book is published by exactly one publisher. Abook is identified by its ISBN, and other attributes are title, price, and number of pages. Each book iswritten by one or more authors; an author writes one or more books, potentially for differentpublishers. Each author is uniquely described by an author ID, and we know each author's name andaddress. Each author is paid a certain royalty rate on each book he or she authors, which potentiallyvaries for each book and for each author. An author receives a separate royalty check for each book heor she writes. Each check is identified by its check number, and we also keep track of the date andamount of each check.TasksDesign a SQL database using the above US superstore sales data set.1.Use Visual Paradigm to draw conceptual diagram2.Use Visual Paradigm todraw ERD

Design your application's/organization's database. You need to create the 3 tables for each of the services offered. You must provide at least 5 examples in each of the table. There must be a table in which you have prices linked to the services you are providing.

Design a survey form of your own. Fill it out as it might have been completed during the database design for Henry Books. For any questions you have too little information to answer, make a reasonable guess. (Ray Henry, the owner of a bookstore chain named Henry Books, gathers and organizes information about branches, publishers, authors, and books. Each local branch of the bookstore has a number that uniquely identifies the branch. In addition, Ray tracks the branch’s name, location, and number of employees. Each publisher has a code that uniquely identifies the publisher. In addition, Ray tracks the publisher’s name and city. The only user of the Book database is Ray, but you do not want to treat the entire project as a single user view. Ray has provided you with all the reports the system must produce, and you will treat each report as a user view. Ray has given you the following requirements: User View 1 Requirements: For each publisher, list the publisher code, publisher name, and…
A company has a number of employees. Each employee is identified by an Emplyee_Id. The companywants to store Employee_Name, Employee_Address, and Employee_BirthDate in the database. Thecompany also has several projects. Each project is identified by a Project_Id. The company wants tostore Project_Name and Project_StartDate in the database. Each employee must be assigned to one ormore projects, or may not be assigned to a project. A project must have at least one employee assignedand may have any number of employees assigned. An employee’s billing rate may vary by project, andthe company wishes to record the applicable billing rate (Billing_Rate) for each employee when assignedto a particular project. Draw an entity relationship diagram (ERD) using crows foot notation for the following situation. Show visible analyst.
A Bank has many customers. Attribute for customer includes customer number, name, address (street, city, state and zip code), sex and date of birth. Customer can have multiple accounts. The bank does not allow join account (one account per customer). Type of account offer by the bank are Saving, Current and Fixed Deposit. Attribute for account are account no, account type, and account balance. Each of the account can only exist in a particular branch. Attribute for branch are branch no, branch name and address (street, city, state and zip code). Customer can open different account at different branch. Draw an ER diagram for the above situation. Identify the entity, attributes, primary key, relationship and multiplicity constraint in the ER diagram.
You are to design a Hospital database. So before creating the database, your task is to draw the ER diagram based on the following data collected and analyzed: A hospital will have a name, unique id, multiple helpline numbers (one for doctor's appointment, one for ambulance, one for bill information and one for other services' info) and locations. A hospital may have more than one location as it may have different branches and each of the locations will have a building no., street address, road no. and city name. A patient will have a name, unique ID, may have more than one phone number, age, height, weight and symptoms. A patient takes an appointment in a hospital and the appointment date is recorded. A patient may have an attendant. An attendant will have his/her name, contact numbers and relationship with the patient as a record in the database. Due to the covid situation, the hospital authorities will only allow 1 attendant with 1 patient.
