COMP2016 Database Management Group Project Assignment
Objective
In this project, we will design and implement a database for a university library.
Requirements
Each book has a call no., ISBN, a title, an author, an amount (amount of copies
available for borrowing), a location (where the book is placed).
For everystudent, we capture her/hisstudent no., name, gender, and major.
When a book is successfully borrowed by a student, a borrow record should
be added to the database. Each borrow record contains at least the following
information: a borrower, a book, a borrow date and a due date (the due date
must be behind the borrow date. The borrow period is four weeks by default).
Once the book is returned by the student, the corresponding borrow record
will be removed.
For each book borrowed, it may be renewed at most one time. When a
renewal is happened, the due date of its corresponding borrow record will be
postponed for two weeks.
Each student may reserve a book if the book is not available for the moment.
A student can reserve at most one book at the same time.
Required Functionalities
Book search: Given a search with ISBN as input, you should tell the
availability of the book. If the book is available, display the title, author, amount,
and location.
Book borrow/return: Given student A and book B, student A can borrow book
B if the following conditions are satisfied:
The available amount of B is larger than 0.
The amount of books student A haven’t returned yet is smaller than 5.
None of the books student A borrowed is overdue.
Book B is not reserved by any students, or Student A is the first one who
reserved B (in this case the corresponding reservation request should be
removed after the book is borrowed).
The corresponding book and borrow records should be updated upon a
successful book borrow/return.
Book renew: Given student A and book B, student A can renew book B if the
following conditions are satisfied:
None of the books student A borrowed is overdue.
Student A hasn’t renewed book B after he borrowed it.
This renewal is allowed only during the 2nd half of B’s borrow period.
Book B is not reserved by any students.
The corresponding borrow record should be updated upon success.
Book reserve: Given student A and book B, student A can reserve book B if the
following conditions are satisfied:
The available amount of B is 0.
Book B is not borrowed by Student A.
Student A doesn’t hold any other reservation request.
The corresponding reserve record should be updated upon success.

Required Trigger
A book borrow/return will trigger the automatic update of the amount of copies
available for borrowing.
System Implementation
Write a Java program (command line interface or GUI) to implement the library
database application and its required functions.
Use JDBC Driver to access the Oracle database from the Java program.
Use PL/SQL to implement the require trigger.
Project Schedule
The project should be carried out in groups of 3-4 members, and includes two phases.
Phase 1: Group forming
Each group should register online, by March 19, 2019.
Successful registration will earn each member 5 marks(out of 100). Those who
fail to register their groups by the deadline will be grouped by random by the
instructor.
Each member of the same group will receive the same mark, so you need to
distribute the work among yourselves evenly. In exceptional cases, if the
members of the same group wish to receive different grades, you should attach
one separate page in the documentation, justifying the reason and identifying
individual contributions (in percentage).
Phase 2: Database design & implementation
You will design an ER diagram, and convert the diagram to relational tables.
All groups must implement a database according to the functional
requirements. This database should support the required functionalities,
including book search, borrow/return, renew and reserve. Also, you need to
implement some triggers to maintain the integrity and consistency of the data.
You are expected to submit a project report and source codes of your developed
system, and demonstrate the functionalities of your implementation. The final
report and demonstration occupy 95 marks.

Submission (due by 5:00PM April 25, 2019)
Each group should submit a compressed file named groupX.zip.
The groupX.zip file should include the following items:
- groupX_source.zip (the Java project source files)
- groupX_dbinsert.sql (the SQL command file for creating your tables, triggers,
constraints and inserting sample data) - groupX_dbdrop.sql (the SQL command file for dropping your tables,
constraints and triggers) - groupX_report.pdf (the project report should include: 1. group members,
including student IDs and names; 2. ER diagram, table schemes,
normalization if any, and the corresponding explanation for helping the
instructor understand your design; 3. source codes, including comments, of all
your implemented functions/triggers and SQL commands)
Note: Replace ‘X’ with your group no. in the above mentioned files.
Submit your compressed file groupX.zip to HKBUMoodle:
https://buelearning.hkbu.edu….
Only ONE submission is required for each group, for multiple submissions, only the
latest one will be collected.
Notes
Plagiarism (complete/partial copying of other people’s work or sharing your
own work with other groups) will get a zero mark.
Late submission will not be entertained.
