**ProgRookie92** · 07-02-2012, 10:54 AM

I don't even know how to do???
Question : There are 2 types of borrowers ; staff and student. A staff can borrow 5 books for loan duration of 1 month whereas a student may borrow 2 books for a loan duration for 2 weeks. Librarian can add books to the library collection or remove them. Librarians and borrowers should be able to use the system to search for books by particular author or on a particular subject. The system should also provide functions to handle the transaction for borrowing books and returning books to the library.
Required
a) identify the entity classes for the library circulation system
b) For each entity class, determine its attributes and operation
c) Create the computerized circulation application

*my tutor told me it is very easy but it seems very difficult to me...Plz help

Appreciate your help....

So start from step A, figure out what classes you need. For most projects, I find the best way to do this is to figure out what objects or people are part of the system. Then, create classes for those. Sometimes, transactions should have classes to represent them. Figure out whether the transactions you're dealing with need a class, and how you'd represent them (with or without their own class) Are any of the objects/people/actions similar? If they are, you probably want them to extend a class with their shared attributes.

From there, figure out what fields you need in each class to represent the data, and the methods that each class need. What parameters do those methods need? What does each method do? How do you handle failure? Figure those out, and write it down somewhere, or make skeleton classes with unimplemented methods and write what they do as comments.

It Seems To Be Easy When U Divide The Work Like this

Staff (Attributes are : id,name,address,designation,dept)

Student(Attributes are : regNo,Name,address,class,yearOfJoining,yearOfEndin g,dept)

Book(id,bookName,Author,dept)

Department(deptId,departmentName)

Borrow(id,Name,type(Student/Staff),startDate(User Have To enter),endDate(Automatically Calculate Based On type),dept)

Return(id,borrowId,returnDate,fineRequired,fineAmo unt)
