Bookshop Management System using File Handling in C++

Introduction

In the rapidly developing digital age, effective management systems play a key role in the organization and efficiency of various business areas. A bookstore management system using file processing in C++ is a project designed to meet the needs of a traditional bookstore by automating and streamlining its daily operations. This system is built on the principles of the C++ programming language and uses file manipulation techniques to store and retrieve information about books, customers, and events. The goal is to create a user-friendly and robust solution that simplifies the tasks of the library and facilitates the interaction of both customers and employees with the system.

System Architecture

Bookshop management system using file management in C++; is built from several interconnected components, each of which fulfills a specific purpose to ensure efficient data management, user interaction, and system functionality.

User Interface (UI): The user interface is the entry point for the user and the system, and provides graphical representations of operations. It contains a main menu with options, such as book, customer management, transactions, and reporting. Entry forms allow users to add, edit, or delete registered entries and customer information. Additionally, user interfaces facilitate user interaction for searching, filtering, event processing, and reporting.
Data management: Data management includes data storage and retrieval. Separate files store information about books, customers, and events. The file processing module reads data during system startup and updates files based on user interactions.
Business logic: The business logic layer contains the basic functions. Books and customer management modules handle operations such as adding, modifying, and deleting. The transaction processing module manages purchase and return transactions and updates inventory and transaction history. The reporting module generates various reports based on the recorded data.
Security: Ensuring secure access and protecting sensitive data are the responsibilities of the security layer. The user authentication module verifies user credentials and monitors system usage. The encryption module protects sensitive data with encryption algorithms.
Error Handling: The error handling layer handles unexpected scenarios and provides user-friendly error messages and hints to solve the problem.
File Updates: The File Updates layer ensures that changes made during user interaction are reflected in data files, thus maintaining data integrity. The file update module coordinates with the file handler to write back changes to the appropriate data files.

Flow of Information

The data flow in "Library Management System Using File Processing in C++" includes several steps, including system initialization and user authentication. The process includes user interactions, data processing, security checks, and file updates. Below is a detailed description of the flow:

System Initialization: The system is initialized by loading existing data from the ledger, customer, and transaction files into memory. It ensures that the system starts with the latest information available.
User Authentication: Users are prompted to authenticate with a username and password. The user authentication module verifies entered credentials and allows access to authorized users.
Main Menu Display: After successful authentication, the main menu will be displayed with various options like book management, customer management, transactions, and reporting.
User interaction: Users interact with the system through the user interface by selecting certain functions from the main menu. Entry forms are used to add, change, or delete book entries and customer information.
Data processing: The selected functions trigger the corresponding modules in the Business Logic Layer. For book management, the book management module handles operations such as adding, editing, and deleting. The Customer Management module handles customer-related functions, and the Transaction Processing module handles transactions.
Security Controls: Access to critical functions is protected by user authentication, which ensures that only authorized users can perform certain functions. The encryption module protects sensitive data and protects it from unauthorized access.
File Updates: Changes made by user actions are updated in memory. The file update module coordinates with the file handler to write these changes back to the appropriate files, ensuring data persistence.
Visual feedback: Users receive visual feedback about the success or failure of their actions. Confirmation messages are displayed for successful transactions, while error messages provide information about failed operations and suggested solutions.
Search and Filter: Users can use search and filter interfaces to find specific books based on things like title, author, or genre.
Event History: The event processing module maintains an event history and records the details of each event, including the event log, event type, and date/time.
Report Generation: Users can generate various reports through the reporting interface that provides information on sales trends, inventory, and other relevant information.

Below is a simplified example to get you started. Note that it is a base image and a complete system would require additional features, error handling and refinements.

#include <iostream>
#include <fstream>
#include <iomanip>
#include <vector>
using namespace std;

// Define a Book structure to store book information
struct Book {
 string title;
 string author;
 string isbn;
 double price;
 int quantity;
};

// Function to add a new book to the inventory
void addBook(vector<Book>& inventory) {
 Book newBook;
 
 cout << "Enter Book Title: ";
 getline(cin, newBook.title);

 // Add the new book to the inventory
 inventory.push_back(newBook);
 
 // Save the updated inventory to a file
 ofstream outFile("inventory.txt", ios::app);
 if (outFile.is_open()) {
 outFile << newBook.title << ',' << newBook.author << ',' << newBook.isbn << ',' << newBook.price << ',' << newBook.quantity << '\n';
 outFile.close();
 cout << "Book added successfully!\n";
 } else {
 cout << "Error: Unable to open the file.\n";
 }
}

// Function to display the inventory
void displayInventory(const vector<Book>& inventory) {
 cout << setw(20) << "Title" << setw(20) << "Author" << setw(15) << "ISBN" << setw(10) << "Price" << setw(10) << "Quantity" << endl;
 cout << setfill('-') << setw(75) << "\n" << setfill(' ');

 for (const auto& book : inventory) {

 }
}
// Function to load inventory from file
void loadInventory(vector<Book>& inventory) {
 ifstream inFile("inventory.txt");
 if (inFile.is_open()) {
 while (!inFile.eof()) {
 Book book;
 getline(inFile, book.title, ',');
 getline(inFile, book.author, ',');
 getline(inFile, book.isbn, ',');
 inFile >> book.price;
 inFile.ignore(); // Ignore the comma
 inFile >> book.quantity;
 inFile.ignore(); // Ignore the newline character

 if (!book.title.empty()) {
 inventory.push_back(book);
 }
 }
 inFile.close();
 } else {
 cout << "Error: Unable to open the file.\n";
 }
}

int main () {
 vector<Book> inventory;
 // Load existing inventory from file
 loadInventory(inventory);
 int choice;
 do {
 cout << "\nBookshop Management System\n";
 cout << "1. Add Book\n";
 cout << "2. Display Inventory\n";
 cout << "0. Exit\n";

Explanation:

The included C++ code forms the Bookshop management system, which embodies the basic principles of object-oriented programming and file handling. The program revolves around the processing and presentation of book data and provides functions to add books to the inventory, display the current inventory, and merge from the system.

Initially, the code uses a structure called Book to encapsulate book-related properties. This structured presentation is an appropriate choice because it allows related information to be consolidated into a single unit, in this case, a book. Attributes include title, author, ISBN (International Standard Book Number), price, and quantity. This encapsulation promotes code organization and readability that are consistent with software development best practices. Moving on to the main features, the AddBook feature is designed to make it easy to add new books to your inventory. It asks the user for information such as book title, author, ISBN, price, and quantity, and then creates a book object with the given information. After that, the newly created book object is added to a vector called inventory, which represents the entire collection of books in the bookstore. However, the importance of this function goes beyond updating the in-memory representation of the warehouse. A crucial aspect is the simultaneous storage of data through file processing. The function opens a file stream (of stream) named "inventory" in attachment mode, where new book information can be added to the end of the file. If the file is successfully opened, the function writes the new book information, separated by commas, and closes the file. This dual feature ensures that the inventory is not only available during program and runtime but also persists across sessions when stored in an external file.

The DisplayInventory function completes the plugin by providing a structured and visually appealing representation of the current inventory. Utilizing the powerful I/O manipulators of title, the function formats and prints the book information as a table, aligning each attribute correctly. Column headings, including "Title", "Author", "ISBN", "Price", and "And quantity" are displayed at appropriate intervals, improving the overall readability of the list. The load inventory function plays a key role in initializing the program and state by reading the existing book data "inventory" file. It opens a file stream (stream), reads the data line by line, and fills the storage vector accordingly. It ensures that the program starts each session with an accurate representation based on the information stored in the library. Using the getline and ignore functions to parse a file is an example of strong file input handling.

The main function is organizing the entire bookstore management system, which acts as a control center. It initializes the inventory vector and loads all available data from the file at the start of the program's execution. The main chain always has a user-friendly menu that allows users to interact with the system. The user can add a new book, show the current inventory, or exit the program. The loop continues until the user decides to exit, ensuring a smooth and user-friendly experience.
