Draw an Entity relationship diagram (ER) for a university according to the following rules: +-- For each student the university needs to keep track of: first name, last name, student id, address, phone no and their major. - The student id is identical for each student. > -- Each course has a number, name and credit. The course number is unique for each course. +-- Each department has a name, code and location. The code is unique for each department. - Each course may has one or more sections where each section is belong to only one course. +--A department offers one or many courses. 7- Some courses have perquisite courses. 8- Each student could register in one or more courses. In your diagram you need to show the following: 1- The primary key for each entity. 2- The cardinality and participation between entities.

Draw an Entity Relationship Diagram for all of those below. Draw an ER diagram to represent information about students. A student is identified by his/her student number. Student’s name (first and last), permanent address, phone number, gender and date of birth are also stored. An airplane has a registration number, type, number of economy class seats, number of business class seats and the year of production. Some students live in student halls. Each hall has a name (unique) and an address. Each student has a number (unique) and a name. Assume that there are students living in every hall. Each text book has a unique ISBN (International Standard Book Number), and contains several chapters. Each chapter has a chapter number (unique within a book), the number of pages and the number of references. A chapter covers a single topic, but the same topic may be covered in various books. Each lecturer is identified by a unique number, name and phone. A lecturer teaches several courses, and for…
Draw a complete ER-diagram for the following case. A lecturer (having an ID, name and room number) is responsible for organizing a number of course modules. Each module has a unique code and also a name and each module can involve a number of lectures who deliver part of it. A module is composed of a series of lectures and sometimes lectures a on a given topic can be part of more than one module. A lecture has a time room and date and is delivered by a lecturer and a lecturer may deliver more than one lecture. Students, identified by number and name, can attend lectures and a student must be registered for a number of modules. We also store the date on which the student first registered for that module. Finally, a lecturer acts as a tutor for a number of students and each student has only one tutor. Also show relational database schema including Primary and Foreign key constraints. (Please draw this on a paper)
Prepare an Entity Relationship Diagram for the application described in the following paragraph. Pick and Shovel Construction Company is a multi-state building contractor specializing in medium-priced town homes. Assume that Pick and Shovel’s main entities are its customers, employees, projects and equipment. A customer can hire the company for more than one project, and employees sometimes work on more than one project at a time. Equipment, however, is assigned to only one project at a time. Draw an ERD showing those entities.
Consider the following entity relationship diagram. Booking Employee Room Building • Booking ID • Employee ID • Building ID • Room ID • First Name • Room ID P • Name Description • Employee ID • Name Last Name • Date • Campus Zone • Email Address • Capacity • Start Time • Map Coordinates Phone • Bookable • End Time For each statement below, use the drop-down box to indicate whether it is true (answer 1) or false (answer2), according to the design decisions encoded in the ERD. Every booking is associated with exactly one employee. ✓ Every employee is associated with at most one booking. ✓ A building may contain no rooms that are recorded in the database. Each room may have many bookings. 1. True ✓ A room must have at least one booking. 2. False ✓ A booking can be associated with many employees. An employee may have no phone number recorded. ✓ A room must have its capacity recorded. ✓ A building is uniquely identified by its map coordinates.
Draw an Entity Relationship Diagram for all of those below. (a simple one) Each lecturer is identified by a unique number, name and phone. A lecturer teaches several courses, and for each course there is a unique code and title (not necessarily unique). There might be several lecturers in a course. Each course requires one or more text books. Each text book is used in at least one course. A text book is identified by a unique ISBN, and its title, authors, publisher and year of publication are known. Each course has a unique code. The bank has many customers. Every customer has at least one account with the bank. An account may be shared by several customers. Each customer has a unique number, type, the opening date and the balance. A flight carries many passengers on a specific airplane. Each airplane has a unique number, while each flight has a code (unique), destination and origin. A passenger has a name, passport number and nationality
Draw an ER diagram that captures the following information: A book identified by (unique Id number, a title and one or more authors), A library identified by (unique name and adders), A borrower has a name and a unique ID code. The library service may own several copies of a given book. A borrower can have many books on loan, but each copy of a book can only be on loan to one borrower. A borrower could borrow the same book on several occasions, but it is assumed that each such loan will take place on a different date. *
Draw an ER diagram on any application for a student information system with 4 entities:-entity class:classID,department-entity department:deptID,Dept_name-entity student:studentID,firstname,last name,gender,birthdate,address,hobby,class,mother name,father name,student code-entity parents:parentID,parent name,occupation,address,town,parent type,gender,telephone,email address
A company makes items. Each item has a name, ID and component quantity. Every item contains many components. Each component can be supplied by one or more suppliers. Suppliers have names and IDS. Each component has ID, name, description, suppliers who supply them, and items in which they are used. Not all suppliers provide components, and a component is not always associated with a supplier. Also, a component always have to be associated with one or more items. Finally, the company contact customers using their IDs, Names and Phones to sell them items. A customer can buy one or more items.
