- You are one of the team members who your project team leader has assigned to involve in the discussion of developing an Automated Teller Machine (ATM) system. Throughout the discussion, you have gathered the following requirements statement for the ATM system from your clients' team members. The IT personnel from your client’s team need to understand the structure of your database and the interaction between the actor(s) or object(s) in the system. Therefore, you have instructed your System Analyst to provide the structural and behavioural modelling of the ATM system based on the requirements statement you gathered, as shown below : AutomatedTellerMachine The software to be designed will control a simulated Automated Teller Machine (ATM) having a magnetic stripe reader for reading an ATM card, a customer console (keyboard and display) for interaction with the customer, a slot for depositing envelopes, a dispenser for cash (in multiples of $20), a printer for printing customer…A public sector hospital wants to automate its manual paper based operations to speed up the operations and facilitate its patients and staff members. For this purpose, they want to develop a database for their hospital management system to remove paper based records. Now, you are required to analyze the following scenario very carefully and draw entity relationship diagram (ERD) for the given system by identifying entities, attributes and relationship among these entities. A hospital consists of various specialized wards where each ward has its unique ID, name and capacity (total number of beds for patients in each ward). Multiple patients can be admitted in each ward on the recommendations of the doctor. Each doctor has a unique id, name, specialization and etc. Furthermore, a specialized team of doctors in each ward will take care of admitted patients and suggest treatment for the patients (such as medication, recommended tests, date of admission, and date of discharge). Each ward…Given the following business scenario, create a Crow’s Foot ERD using a specialization hierarchy if appropriate for one case study.DB for Railway ReservationPurpose: The Database is for a railway reservation system which facilitates the passengers to enquire about the trains available on the basis of source and destination, booking and cancellation of tickets, enquire about the status of the booked ticket, etc. The database is for maintaining the records of different trains, train status, and passengers. The record of train includes its number, name, source, destination, and days on which it is available, whereas record of train status includes dates for which tickets can be booked, total number of seats available, and number of seats already booked.Passengers can book their tickets for the train in which seats are available. For this, passenger has to provide the desired train number and the date for which ticket is to be booked. Before booking a ticket for a passenger, the validity…

- The individual has been appointed as a Database Developer and has been presented with the option to employ either a trigger or a procedure in their development tasks. Define triggers and identify the optimal circumstances for their utilization?Consider a school system in which data is recorded about the movie industry. The data requirements are summarized as follows: Each subject is owned by a department and each department ismanaged by a teacher, called Head of Department (HOD). Eachdepartment has a name and a unique code number. Each subjecthas a name, unique number and credit value. All teachers have aunique ID. A HOD cannot manage more than one department at atime. Also, a HOD does not teach subjects. A subject cannot betaught by more than one teacher. Finally, the system needs toknow each student’s contact details, including, full name, studentID, address, age and gender, as well as date of enrolment in thesubject. Design an Entity-Relationship diagram for the movie databaseAir-india want to create database to stores details about an airline’s fleet, flights, and seat bookings. Again, it’s a hugely simplified version of what a real airline would use, but the principles are the same. Draw an ER diagram based on the information given.Consider the following requirements list: • The airline has one or more airplanes.• An airplane has a model number, a unique registration number, and the capacity to take at most 100 passengers.• An airplane flight has a unique flight number, a departure airport, a destination airport, a departure date and time, and an arrival date and time.• Each flight is carried out by a single airplane.• A passenger has given names, a surname, and a unique email address.• A passenger can book at most 5 seats on a flight.[7](b) Convert the diagram 1(a) in relational model.
