The quiz will be open in week 9laboratory class.Part B: (70 marks)1. Database DesignThe School of Information Technology & Engineering (SITE) would like to help its Master of Networkingstudents with placement in various companies and firms. To facilitate this, they need to design a databasewith the primary purpose of scheduling interviews and facilitating searches by students and companiesthat are looking for candidates. MIT’s IT Manager provided following business rules to the softwaredeveloper:Complete the information-level design for the new database “MIT training” that satisfies the constraintsand user view requirements given below. In order to complete the information-level design you arerequired to answer questions given below.User view 1 requirement: The database should have information about students, job openings,companies, interviewers and interviews. Student’s first name, last name, student id number, driver’slicense number and expected graduation date must be recorded.User view 2 requirements: Companies post job openings that students can apply for. For each job posting,the date, application deadline of the posting, title of the position, base salary, minimum requirements,and description are recorded.User view 3 requirements: One student can apply for many open positions (Job postings) in differentcompanies, and the date and time of each application is recorded. Students should also be able to see thestatus of their application (whether there will be a follow-up interview and whether they were turneddown for the position).User view 4 requirements: Interviews can be facilitated by the University and interviews are conductedby the respective companies. It is required to keep track of date and time of the interview, conferenceroom location, which employees interviewed which students, as well as the result of the interview. Acompany from the Business School reserves MIT conference rooms and the company needs to specify theresources needed (e.g. computer, projector, etc.).User view 5 requirements: An interviewer is an employee of a company and he/she has an employeeid, telephone number and position title.User view 6 requirements: A company has an identifier, name, main contact number and main faxnumber.Write down any assumptions you have made, if they are not explicitly described here.While completing the information-level design you are required to answer questions givenbelow 1(a) – (c)BN204 Database Technologies Page | 4 of 4Prepared by: Dr. Deepani Guruge Moderated by: Prof. Paul Kwan April, 2021a. Identify and list entities described in the given case scenario.(5 Marks)Outline at least 2 business rules that describes relationships between entities and write the typeof the relationship. Eg (1:1, 1:M or M:N)(5 Marks) b. c. ER diagramAdd attributes to those entities and select suitable primary keys for each entity.Represent the structure of your database visually by using the entity-relationship (ER) diagram.I. If you make any assumptions about data that are not explicitly given in the problem,these must be described.II. You are required to use a software tool to create the ER diagram. You can usedraw.io, Lucidchart , Visio or any other software tool to create the ER diagram.(15 Marks)2. Data Integritya. Represent entities and attributes as collection of tables and attributes as given below. Eg.Student (Stu_ID, Sname,…….NB: Select suitable primary key for each table and underline them.(5 Marks) b. Determine the functional dependences. (5 Marks)Eg. Stu_ID — > Sname, , ……, ……c. Normalise these tables. Make the normalization to 3NF and explain every step in the process.(10 Marks)3. Model Building Build this model using MS Access/SQLite by creating these tables and Relationships.Populate these tables with appropriate data, at least 2 records in each table.Include following into your MS Word document. (10 Marks)I. If you are using MS Access include following screen shots Relationship diagram created in Access. (Select database tools Relationships in theAccess menu)Data sheet view and design view of your tables as given below in Figure 1 and 2. For Student_Name and Student_ID you need to use your MIT ID and your name as onedata record.Figure 1 Data Sheet View Figure 2 Design ViewII. If you are using SQLiteBN204 Database Technologies Page | 5 of 5Prepared by: Dr. Deepani Guruge Moderated by: Prof. Paul Kwan April, 2021 Include screen shots of CREATE TABLE command and INSERT INTO commands.Eg.4. Report Generationa. Write a query to extract useful information from this “MIT training” database. (3 Marks)b. Execute this query on the database and attach the screenshot of your output. (3 Marks)5.

What are “indoor positioning systems” and why have researchers indicated that, they areimportant? (5 Marks)b.
