Big Data Processing One of the benefits from Graph Database is it is significantly faster than traditional RelationalDatabase System (RDBMS), especially for a database with many relations. Create a graph database of the following RDBMS tables with 3 records for each table. The Entity Relationship Diagram represents an Online Course Database. Use a graph diagram that consists of vertices and edges torepresents the graph database. Explain why a database query would be executed significantly faster in the Graph Database than the RDBMS based on the example database.

ER Diagram You are working for DroneCore, a new startup that provides a backend for drone-based companies in towns and cities around the world. Your employer tasks you with designing a database for this service. Given the following information, draw the ER diagram: Any given startup should store information about Drones, Hubs, Employees, History entries, and Users. A Hub has an ID associated with it. A Drone has an ID, a model, a purchase date, and an assigned Hub, which it operates out of. Each Employee has an ID, a name, and a salary, and works at a specific Hub. Employees may also maintain a set of Drones. An employee can maintain any number of drones, but each drone must be maintained by exactly one employee. Each User has an ID, a name, and a preferred Hub. The company stores delivery History. A history item tracks a Drone's delivery to a User, and stores the departure time, the delivery number, time of arrival, and return time. This is MYSQL

Attracted by the success of Spotify, a group of students want to build their own music-streaming website called Musicmatic. Being economists, they are unaware of the specificities of databases and have therefore asked you to create an EER model. A large number of songs will be made available through their website, and the following information on each song needs to be stored: title, year, length, and genre. Also, artist information will be added, including date of birth, name, and a URL to a website (e.g., Wikipedia page) with additional information on the artist. You can assume an artist is uniquely identified by her name, and that a song always belongs to exactly one artist. The Musicmatic students also point out that songs having the same title are possible, and only the combination of song and artist can be assumed to be unique. The database will also have to store information on the people using Musicmatic. It was decided to only discriminate between two types of users: regular…

DataBase case study: read this case study and finilize what should be the enitties that is mentioned in the case study and then make a ERD daigram of this data.   Delhi Mart is a super Store located at Mahavir Enclave, New Delhi, India.  Delhi Mart has many types of products that are related to specific Category.  Delhi Mart are avail many different customers to sell their products daily. Every Category is managed by a particular manager. Customer order their selected product in terms of qty and avail selected discount on the product.  Delhi Mart also have staff that manage different departments in the mall. Every Customer is concern with a particular staff to resolve their queries. Every Manager is responsible to maintain the stock if the stock will out they contact their selected supplier for buying products.

Hi please assist with a and b thanks Computer Science Question Datadyne inc. is a large company that has a system to manage its Data Warehouse. They would like to make some form or upgrade to the system that would enable them to streamline the way in which they perform operations as well as have a means to log which operations being done, and have been performed. One of your colleagues has suggested the following as suitable candidates for a Design Pattern to apply: Observer Design Pattern Object Pool Design Pattern Command Design Pattern (a) Which do you think is the most optimal design pattern? (b) Discuss why you think this is an appropriate design pattern

A dimensional model is used in the building of a data warehouse, but what exactly does it do?

A dimensional model is employed in the construction of a data warehouse, but what precisely does it perform is unclear.

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.…

Relational Schema NormalizationWhen a database is “normalized” it is restructured (according to a series of normal-forms, whichwe do not discuss here) in order to reduce data redundancy and improve data integrity.Typically this means decomposing one table into two or more new tables that are newly related.You must employ the following normalizations when reducing your ER diagram to a finalrelational database schema diagram:● You must further normalize (or decompose) the sales_persons, customers, drivers,contractors, and shipments tables, so that all addresses are maintained in a new tablecalled “addresses”. In doing so, each of these five tables newly participates in amany-to-one relationship with the addresses table. The primary key of the newlycreated addresses table is called address_id and is a unique identification numberarbitrarily assigned by the logistics company.● In this assignment, all relationship sets will be eliminated from the final database design.This will be done by…

Database Design   Testing (ID_testing,date,observerId) Observer(observerId,observer_name) Type(TypeId,typename) Essentialoil (ID_essential,essentialname,typeId,batchcode) Constituent (ID_constituent,cname,min_percentage,Test_percentage,status)   Before an Essential Oil product is marketed, testing is carried out based on the production batch from any essential oil. This is done to maintain the quality and content of the existing constituents in essential oils. Where the Test Percentage Content must reach the Minimum standard Percentage Content for each constituent. If there is one type of constituent that does not fulfill minimum standard, the batch will not be marketed because it does not meet the standard quality. Question 1. Make an ERD (Entitiy Relationship Diagram) based on the results of Normalization 2. Develop the ERD that you create to implementGeneralization / Specialization.
