Consider a database that includes the entity sets student, course, and section from the university schema and that additionally records the marks that students receive in different exams of different sections. a. Construct an E-R diagram that models exams as entities and uses a ternary relationship as part of the design. b. Construct an alternative E-R diagram that uses only a binary relationship between student and section. Make sure that only one relationship exists between a particular student and section pair, yet you can represent the marks that a student gets in different exams.

Q. 1 Consider a university database for the scheduling of classrooms for final exams. This database could be modeled as the single entity set exam, with attributes course-name, section-number, room-number, and time. Alternatively, one or more additional entity sets could be defined, along with relationship sets to replace some of the attributes of the exam entity set, as1. course with attributes name, department, and c-number2. section with attributes s-number and enrollment, and dependent as a weak entity set on course3. room with attributes r-number, capacity, and buildingShow an E-R diagram illustrating the use of all three additional entity sets Listed and also specify the primary keys all

Consider a database schema with a relation Emp whose attributes are as shown below, with types specified for multivalued attributes. Emp = (ename, ChildrenSet multiset(Children), SkillSet multiset(Skills))Children = (name, birthday)Skills = (type, ExamSet setof(Exams))Exams = (year, city) Redesign the database above into first normal form and fourth normal form. List any functional and multivalued dependencies that you assume. Also list all referential-integrity constraints that should be present in the first and fourth normal form schemas.
our task for this assignment is to complete a database design for the given case studies. Model the system described in the case study and draw a Physical Data Model using MySQL Workbench. Your diagram must conform to the notation used in this subject (object notation = ‘Workbench Simplified’, relationships notation = ‘Crows Foot’, show data types). If you include sub-types, place them inside a Layer with a note explaining their relationship to the super-type.
Draw an ER diagram and then map it into a relational schema(database) for the following scenario.• For each MEMBER we keep track of the unique MemdID, a well as Name, Zip, and the Datethe membership was paid.• For each MEMBERSHIP type we keep track of the unique Mid, as well as MName and Price• For each PASS CATEGORY we keep track of the unique PassCatID, as well as PCName andPrice• For each ONE DAY PASS we keep track of the unique PassID and Date• For each MERCHANDISE item we keep track of the unique MrchID, as well as Name andPrice• For each sale TRANSACTION we keep track of the unique Tid and Date• Each member pays for exactly one membership type; each membership type has at leastone member but can have many members.• Each member can buy many day passes but does not have to buy any, each day pass wasbought by exactly one member• Each day pass belongs to exactly one pass category; a pass category can have manyindividual day passes issued for it but does not have to have any. • Each…
Construct an ER Diagram from the following case study A new established company database needs to store information about employees (identified by NIC, with salary and phone as attributes), departments (identified by dno, with dname and budget as attributes), and children of employees (with name and age as attributes). Employees work in departments; each department is managed by an employee; a child must be identified uniquely by name when the parent (who is an employee; assume that only one parent works for the company) is known. We are not interested in information about a child once the parent leaves the company.
Should the cardinality between entities be translated/read from both ends of the notation when dealing with database entity relationship modelling? In other words, should a relationship between things be understandable when read both forwards and backwards?
Design an Entity-Relationship diagram for the below environment. determine 1-Total participation.2-Partial participation Consider a MAIL_ORDER database in which employees take orders for parts from customers. The data requirements are summarized as follows: o The mail order company has employees, each identified by a unique employee number, first and last name, and Zip Code. o Each customer of the company is identified by a unique customer num, first and last name, and Zip Code. o Each part is identified by a unique part number, a part name, price, and quantity. o Each order placed by a customer is taken by an employee and is given a unique order number. Each order contains specified quantities of one or more parts. Each order has a date of receipt as well as an expected ship date. The actual ship date is also recorded.
Given the database schema with the following relations: STUDENT (id_stud, name_stud) LECTURER (id_lect, name_lect) SUBJECT (id_subject, id_lect, name_subject, credits, id_room) ROOM (id_room, no_room) ENROLL (id_stud, id_subject) Create an algebraic relation for: a. Displays all names of lecturers who teach the subject with a total of 4 credits b. Displays all no_room with the student name "Eko" c. Displays all data in the form of student id, student name, name of the course followed and the name of the lecturer who taught the subject name "Database" From the database schema and the questions above, create an appropriate SQL query for each of these statements above.
