SQL for Library Management: Cataloging Mastery-SQL Library Management Mastery

Example

CREATE TABLE Books (BookID INT PRIMARY KEY, Title VARCHAR(255), Author VARCHAR(255), ISBN VARCHAR(20), PublishedYear YEAR);

Scenario

Designing a table schema to store essential details of books. This schema supports queries for book availability, bibliographic details, and helps in inventory management.

Example

CREATE TABLE Authors (AuthorID INT PRIMARY KEY, Name VARCHAR(255)); CREATE TABLE BookAuthors (BookID INT, AuthorID INT, FOREIGN KEY (BookID) REFERENCES Books(BookID), FOREIGN KEY (AuthorID) REFERENCES Authors(AuthorID));

Scenario

Normalizing data to avoid redundancy and enhance data integrity. For example, separating book and author data into two tables linked by a junction table allows for multiple authors per book without duplicating book data.

Example

CREATE TABLE Loans (LoanID INT PRIMARY KEY, BookID INT, UserID INT, LoanDate DATE, DueDate DATE, FOREIGN KEY (BookID) REFERENCES Books(BookID), FOREIGN KEY (UserID) REFERENCES Users(UserID));

Scenario

Managing book loans by tracking which user has borrowed which book and when it is due back. This function facilitates effective monitoring and management of borrowed items, reducing overdue loans through timely reminders.
