- A common database environment should have at least the following nine elements.Airline Reservation System In this project, you will design and implement a simple interactive airline reservation system similar to orbitz (www.orbitz.com). The system is a typical client-server application with a web-based front-end for the user and a database backend. This project will focus only on the backend and NOT on the front end. This document provides a high-level description of the project and outlines the deliverables expected of your team. It is crucial that you have a good solid design before you start coding. The purpose of the online system is to create convenient and easy-to-use online system for passengers, trying to buy airline tickets. The system is based on a relational database with its flight management and reservation functions. We will have a database supporting dozens of major cities around the world as well as hundreds of flights by various airline companies. Above all, we hope to provide a comfortable user experience along with the best pricing available.…The third tier in a three-tier scheme is the intermediate layer between the database and the client servers.
- pls help You have been hired by a doctors office to analyze the current state and determine requirements for a Patient booking system. In creating models that reflect the current state you draw a circle in the center of the page. You then draw things around the circle. The things around the circle are called A closed system Something that sits next to the database An actor A ThingA database's connections may be generic, non-identifying, or identifying.An intermediary stage may be thought of as a layer between the database and the client servers.
- DATABASE MANAGEMENT Design an EER diagram for a database used to manage a racket sport association (for example, US Tennis Association). The following is a list of simplified requirements. Each member of the sport association has an id, a name, sex, age, an address, a phone number. A member can be a player, an umpire (i.e., referee), a coach, or an officer (i.e. a member can belong to one or more of the above categories). An umpire has a type (i.e., national, international, etc.). A coach has a certificate (i.e., level I, II, etc.). An officer has an office (i.e., a room number such as 101 or 212 in the main building). Each club has a name, an address, an owner, and a phone number. Except for some officers, every member belongs to one or more clubs (Hint: Make relationships between the subclasses of “member” and club). A player can be a professional or an amateur (but not both). A professional player has a rank (such as 1, 2, etc. within the association), and a coach (Note: Every…A database design is created by following the conversion of a data model to a database design.A top-to-bottom relationship forms a link between the components in a database.
