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. *
Each department runs a number of courses. The university provides a set of modules used in different courses. Each course uses a number of modules but not every module is used. A course is assigned a unique course code and a module is identified by a unique module code. A module can be used in one course only, but can be studied by many students. In addition to the module code each module unique title, start date, end date, texts (books), and assessment scheme (i.e., coursework and exam marks percentages) are also stored.
Each course is managed by a member of academic staff, and each module is coordinated by a member of academic staff also. The database should also store each course unique title, and duration (in years).
A student can enroll in one course at a time. Once enrolled a student is assigned a unique matriculation number. To complete a course, each student must undertake and pass all the required modules in his/her course. This requires that the database store the…
An E-learning website needs your help to design its database. They need to store information about teachers and online tutorials. Each teacher has a unique ID, name, and at least one field of specialty. Teachers form groups to prepare online tutorials. Each group has unique name and at least one teacher as a member. Each online tutorial has a title, date and organized by exactly one group. The title of the tutorial is unique for the group. Each tutorial consists of several sessions, described by their titles and durations. Naturally, each session is presented by one teacher and belongs to exactly one tutorial. In addition, sessions on the same tutorial have different titles.
Design an ERD for this application. Note any unspecified requirements, and make appropriate assumptions to make the specification complete.

Course offerings, including course number, year, semester, section number, instructor, timings and classroom. Students, including student-id, name, and program. Instructors, including identification number, name, department, and title. Furthermore, the enrollment of students in courses and grades awarded to students in each course they are enrolled for must be appropriately modeled.
