- SUBJECT: SOFTWARE ENGINEERING PROCESS Given the following scenario: In campus management system, one of the work flows has following description; A Student submits admission form to apply for admission in university. The form is evaluated and approved forms are shortlisted. Shortlisted students are invited for interview. After interview of students, selected forms are stored in database. You are required to draw a Data Flow Diagram of above scenarioCreate an ER diagram that correctly describes the database for exams at Campus in Bäcksvängen in accordance with the following description: (Own assumptions must be clearly described.) Staff for various functions are involved in the exams. All staff have a full name and a unique staff code. Some people are examiners on one or more courses. A course has one name and one unique ladok code. For a course, you can add up its points based on the associated elements. One part is part of a course (for example an exam, a laboratory or project). A course can have several different parts. An element has a name, a description, a torque code, one point and two or more grades (eg: U, G, VG). An element can only belong to one course. Since the database is to process the exams, it is obvious that a part like described as an examination has an examination opportunity that is identified, among other things, by the date, start time, end time and that it is possible to calculate total writing time. A…Problem: design a er diagram for a database to keep track of building inspections required by a department of Damaged Buildings (DB). DB building inspections are requested by builders every month. Each building inspection is either passed or not. Inspections have a type code (3 characters, e.g. PLU, FRM, ELE, etc.) and possibly sequencing requirements. Some inspections cannot be performed before other inspections, e.g. final plumbing inspection cannot be performed until the framing inspection is passed. Each inspection has a numeric score, with 75 or more out of 100 being sufficient for a pass status. Each inspection data contains the date of inspection, inspector identification, inspection score, and textual information about the inspection. The textual information can be updated later, but the score can never be changed. FODB maintains a pool of inspectors. Each inspector has a unique 5 digit employee ID, name, and date they were hired. They can conduct any type of inspection but…
- Direct connections between external entities and the database are not permitted under any circumstances. It should be kept in mind as one of the data flow diagram design concepts to consider. What do you think the repercussions of this suggestion will be?A relational database is to be designed for a medium sized Company dealing with industrial applications of computers. The Company delivers various products to its customers ranging from a single application program through to complete installation of hardware with customized software. The Company employs various experts, consultants and supporting staff. All personnel are employed on longt erm basis, i.e. there is no short‐term or temporary staff. Although the Company is somehow structured for administrative purposes (that is, it is divided into departments headed by department managers) all projects are carried out in an inter‐disciplinary way. For each project a project team is selected, grouping employees from different departments, and a Project Manager (also an employee of the Company) is appointed who is entirely and exclusively responsible for the control of the project, quite independently of the Company's hierarchy. The following is a brief statement of some facts and…Suppose 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.
- Consider a PUBLICATION COMPANY database in which data requirements are summarized as follows: Every topic should contain name, code and research area. The topics can have several reports and the reports may contain several topics in them. The report should have a title. A department can publish more than one report. A report can be published only by a single department. The department must have its name and address. Reports can be written by many contractors and contractors can write many reports. Each contractor should have name and address. A publication can include several topics and a topic can be present in more than one publications. A publication must have its title and code. One department can have many publications and a publication can be made only by one department. Construct an E-R diagram (based on a Chen's model) to represent the above requirements. Make sure you include all appropriate entities, relationships, attributes, and cardinalities.Write the proper sequence of activities for the design of a video rental database. (The initial ERD was shown in Figure 9.9.) The design must support all rental activities, customer payment tracking, and employee work schedules, as well as track which employees checked out the videos to the customers. After you finish writing the design activity sequence, complete the ERD to ensure that the database design can be successfully implemented. (Make sure that the design is normalized properly and that it can support the required transactions.)No external sources may establish a direct link to the database. It's a consideration for any data flow diagram creators out there. What does this suggestion imply?
- Draw the Level 0 and Level 1 Data Flow Diagram for the Omantel Billing System Scenario: The teacher uploads the eLearning question, which is then saved in the QUESTIONS database, and informs the students that the quiz is now available for them to take. When taking the quiz, the student will be randomly assigned questions from the QUESTIONS database. All of the student's answers will be saved in the ANSWER database. The system will automatically mark the quiz by accessing the student answers from the ANSWER database and the correct answer from the Question database, after which the system will notify both the teacher and the student of the results.Here is the database design for the personnel data: employee(id, name, address) employeeMap(id, confidentialId) empSalary(confidentialId, salary) The role 'Clerk' would be granted SELECT, UPDATE, DELETE to employee table and granted SELECT to empSalary table. While the clerk can see salary information for any statistical analysis (e.g. average salary computation), he has no idea which employee the salary is for. The role 'Administrator' is granted rights on all three tables; using the confidentialId in the employeeMap table, she has access to salary data for individual employees too. A SQL query that the administrator can use to access all employee fields is: select e.id, e.name, e.address, es.salary from employee e inner join employeeMap m on e.id = m.id inner join empSalary s on m.confidentialId = s.confidentialId; Can you draw a database schema?Task 1: ER diagram for give scenario Consider building a database for a shopping mall with requirements as follows: Each product of the shopping mall has a unique project No, and also has a name, a supplier name, a category, a purchase price and a selling price.

A purchase order for product from a supplier has a unique order No, and a date. The order specifies one or more products and their quantities required for a product. A sales order for product to customers has a unique order No, and a date. The order specifies one or more products and their quantities required for a product The shopping mall has warehouses.
