TASK 2
Design a database to store student personal details, module details, and
assessment results for the students taking the Data Management degree (you can
swap this with your own degree if it is different).
Implement your tables as data frames. Write code to simulate random test data
and use it to populate your database. Ensure you enforce referential integrity.
Using your simulated data, create at least two charts showing information on
module assessment results.
Use R Programming language strickly not use c++
Your Division Head's point of view is as follows: "Pictures are stored in a database, and the basic design/structure we chose includes some very sensitive driver information." What if we placed it in its own folder, out of reach of people who shouldn't have access to it? What would your stance be, or, more precisely, which strategy would you prefer? It is necessary to present justification.
You are required to develop an emergency shelter management system based on layout as illustrated in Figure 2. Let assume the victim’s data have been stored in the system using an array data structure.

- Give Authentic and relevant answer. DATABASE SYSTEMS Construct an Enhanced ERD along with Possible entity clusters of the given below system. This describes the business process to publish an academic paper. The author submits a paper to an editor of a journal. The editor first checks whether the paper fit the theme of the journal. If not, the editor rejects the paper. Otherwise, the editor assigns the paper to a number of reviewers. The reviewers review the paper, and write a review. The review is sent to the editor. The editor then assesses the quality of the paper with the help of reviewers’ comments. If the quality is good, the paper will be accepted, and the author notified. Furthermore, the paper is forwarded to the publisher for publication. If the quality is bad, the editor rejects the paper.arrow_forwardYou are required to design and implement a database system for a pharmacy shop with only one branch. The following is the description from the manager, Mr. Seth Akoto. “here, medicines that require prescriptions are sold only to people that have prescriptions. It is the pharmacy attendant that serves customers when they enter the pharmacy. Usually, people walk in and either give the prescription or mention the medicine they wish to purchase. The worker then searches to see if the medicine is in stock. If in stock, worker accepts payment from customer and gives the medicine and a receipt to the customer. “ 1. Determine all the entities from the description given by Mr. Akoto. 2. Assuming Mr. Akoto only wants a database system that would keep records of medicine{name of medicine, amount in grams in stock} and purchases{medicine bought, amount in grams bought, who attended to customer, when it was sold, contact and name of customer that bought the medicine} a.

The bank has several branches. A branch is identified by its code that is unique for a given bank. The branch name and address are also stored in the database. Customers deal with the bank through the bank branches. So, a customer belongs to a specific bank branch. Customers either open bank accounts (CURRENT, SAVINGS, etc.) or receive bank loans (DIRECT, INDIRECT, etc.) from the bank. The bank stores customer info namely: EID, name, phone, and address. The bank also keeps track of customers’ loans and accounts. Information stored about loans include loan no, amount, and type. Account information stored is account no, balance, and type. The address information stored for any entity includes street number, street name, PO Box, city, and emirate. Draw an ER diagram representing the needed database.arrow_forwardProjectarrow_forward
- 1. You want to design a database for a restaurant. Customers have em password. Each customer can have several credit cards registered in the system, each credit card has a 16 digit number, an expiration date, a 3 digit number (CVC code), and the name on the card. The menu items have a short description, a long descriptioin and a price. Customers can place orders that have the date/time that they were placed, one or several menu items (for each menu item it also keeps the quantity), and the total price (summation of the prices of the items mutiplied by the quatity of each item). There are two types of orders: dine-in, or pick-up. In the case of pick-up orders the system must have the car make, model, and color of the person picking up the order, as well as a parking spot number. Dine-in orders have a tip. In addition, the system needs to know if an order has been paid or not. Draw a complete ER diagram. Your diagram must include ISA relationships. If you need to make additional…arrow_forwardASS -3 Consider the person database with info table has been created. Develop a web application with functions such as that.

- Problem 8-10 use the same database. Let a database application have the following entities Sales = (Customers, Salesperson, Retail Order, Items), which contains the information that a salesperson sells multiple items (tables, computers,...) to customers. There are many customers. There are many salesmen. There are many items. For example, John sells to Joe, Smith sells to Jane, The "Salesperson" will sale many times. The "Customer" can come back and buy items many times The "Retail Order" specifies which Salesperson sell to which customer. In each "Retail_Order", many items (tables, computers,...) can be sold Hint: This is very similar to one of your homework What is the relationship between Retail_Order and Items? One-to-many relationship None of the above One-to-one relationship Many-to-many relationshiparrow_forwardFor each item below, specify whether the statement is true (T) or false (F). A Database Schema keeps the data in a database. Each Data Model is based on a Database Management System (DBMS). Oracle and MYSQL are two of the most popular Data Models. JDBC is a Data Manipulation Language (DML) developed for Java. Database Users may desire to perform conflicting operations at the same time. For example, in an Airline Reservation System, two on-line users may see the last empty seat while trying to reserve a seat on a flight. Security features of a DBMS prevents them from reserving the same seat, therefore avoiding inconsistent database states. In the Entity-Relationship Model (E-R), any distinguishable abstract or concrete thing is called an entity set/type. In the Entity-Relationship Model (E-R), an Attribute maps an entity to another entity (or a set of entities). A Relationship, on the other hand, maps an entity to a primitive value. "many to many" relationships in E-R map each instance…arrow_forwardSuppose you are asked to design a club database system based on the following information. Each student has a unique student id, a name, and an email; each club has a unique club id, a name, a contact telephone number, and has exactly one student as its president. Each student can serve as a president in at most one of the clubs, although he/she can be the members of several clubs. Clubs organize activities and students can participate in any of them. Each activity is described by a unique activity id, a place, a date, a time and those clubs that organize it. If an activity is organized by more than one club, different clubs might contribute different activity fees.QuestionDraw an E-R diagram for the system according to the above description.arrow_forward
