Include appropriate tables, fields, and relationships. To design a school library database schema that can efficiently manage books, students, borrowings, and fines, we need to consider the following entities and their relationships: 1. **Books Table**: Stores information about each book in the library. 2. **Students Table**: Stores information about each student who can borrow books. 3. **Borrowings Table**: Tracks each borrowing of a book by a student. 4. **Fines Table**: Tracks any fines incurred by students for overdue books. Let's break down the schema design step by step: ### Database Schema 1. **Books Table** - **BookID** (Primary Key, integer) - **Title** (string) - **Author** (string) - **ISBN** (string, unique) - **PublicationYear** (integer) - **Genre** (string) - **Status** (enum: Available, Borrowed, Lost) 2. **Students Table** - **StudentID** (Primary Key, integer) - **FirstName** (string) - **LastName** (string) - **DateOfBirth** (date) - **EnrollmentYear** (integer) - **Address** (string) - **PhoneNumber** (string) 3. **Borrowings Table** - **BorrowingID** (Primary Key, integer) - **BookID** (Foreign Key referencing Books.BookID, integer) - **StudentID** (Foreign Key referencing Students.StudentID, integer) - **BorrowDate** (date) - **DueDate** (date) - **ReturnDate** (date, nullable) 4. **Fines Table** - **FineID** (Primary Key, integer) - **StudentID** (Foreign Key referencing Students.StudentID, integer) - **FineAmount** (decimal) - **DateIncurred** (date) - **PaymentStatus** (enum: Unpaid, PartiallyPaid, Paid) ### Relationships 1. **One-to-Many**: A book can be borrowed by multiple students, but each borrowing is linked to a specific book. - **Association**: `Books.BookID` is a foreign key in `Borrowings`. 2. **One-to-Many**: A student can borrow multiple books, but each borrowing is linked to a specific student. - **Association**: `Students.StudentID` is a foreign key in `Borrowings`. 3. **One-to-Many**: A student can incur multiple fines, but each fine is linked to a specific student. - **Association**: `Students.StudentID` is a foreign key in `Fines`. ### Example SQL Statements for Creating Tables ```sql CREATE TABLE Books ( BookID INT PRIMARY KEY, Title VARCHAR(255), Author VARCHAR(100), ISBN VARCHAR(13) UNIQUE, PublicationYear INT, Genre VARCHAR(100), Status ENUM('Available', 'Borrowed', 'Lost') DEFAULT 'Available' ); CREATE TABLE Students ( StudentID INT PRIMARY KEY, FirstName VARCHAR(50), LastName VARCHAR(50), DateOfBirth DATE, EnrollmentYear INT, Address VARCHAR(255), PhoneNumber VARCHAR(20) ); CREATE TABLE Borrowings ( BorrowingID INT PRIMARY KEY, BookID INT, StudentID INT, BorrowDate DATE NOT NULL, DueDate DATE NOT NULL, ReturnDate DATE, FOREIGN KEY (BookID) REFERENCES Books(BookID), FOREIGN KEY (StudentID) REFERENCES Students(StudentID) ); CREATE TABLE Fines ( FineID INT PRIMARY KEY, StudentID INT, FineAmount DECIMAL(10, 2) NOT NULL, DateIncurred DATE NOT NULL, PaymentStatus ENUM('Unpaid', 'PartiallyPaid', 'Paid'), FOREIGN KEY (StudentID) REFERENCES Students(StudentID) ); ``` This schema ensures that the library system can effectively manage books, student information, borrowing transactions, and any associated fines. - Cuplikan Gratis dan Subtitle Bahasa Indonesia srt.
