3. Entities and Relationships
3.1 Entities
1. Students: Students have a unique student id and password, using which they login into
the Library system. They have certain privileges like searching for publications (books,
Journals and conference papers), rooms and cameras. They can checkout, reserve or
renew these resources.
2. Faculty: Faculty have a unique faculty id and password with which they login. They
have the same privileges like students with some additional privileges like reserving a
book for a course.
3. Books: Books have a unique isbn which is used to identify them. They also store the
library name which indicates the library in which they’re available. The attributes of
books are edition, year of publication, author, title, book type, total number and
available number.
4. Journals: The journals table has similar attributes to the Books entity. The only
difference is that there is a unique issn instead of the isbn in the books table. Journal
type indicates if it’s a hard copy or an electronic copy.
5. Conference Proceedings: Conference papers are identified using the unique attribute
conf_paper_id. The other attributes of this entity are conf_name, authors, year of
publication title and conf_type. Conf_type like journals and books indicates if it’s a hard
copy or an electronic or both.
6. Rooms: The primary key for Rooms table is room_num, library name. The other
attributes include capacity,floor number and room type. Students can only reserve
study rooms whereas faculty can reserve both study rooms as well as conference
rooms.

attributes like library name, make, model, lens config and memory.
