The developers opted for a custom approach, eschewing pre-built frameworks or marketplace engines, to create a platform that caters specifically to textbook exchange.
Technology Stack
- PHP: Serves as the primary server-side scripting language, handling requests, managing user sessions, processing form data, and performing backend logic.
- JavaScript: Enhances the user interface with interactivity, enabling features like dynamic search, filtering, form validation, and asynchronous data updates (AJAX).
- HTML/CSS: Structures and styles the web pages, ensuring user-friendly navigation and responsive layout suitable for various devices.
- SQL: Manages the database where listings, user accounts, transactions, and other data are stored and retrieved efficiently.
Key Features
- User Registration and Profiles: Students can create accounts to buy or sell books, manage listings, and track transactions.
- Book Listings: Sellers can post used textbooks with details like title, author, edition, price, condition, and optional photos.
- Search and Filtering: Buyers can search for books by keywords, course names, ISBN numbers, or filter by price, condition, and seller location.
- Secure Messaging: A built-in communication system allows buyers and sellers to negotiate prices or discuss the condition before a transaction.
- Transaction Management: Although payment processing might be handled externally or offline, the system tracks the status of sales for both parties.
- Mobile-Friendly Design: Responsive layouts ensure usability on smartphones and tablets, crucial for busy students.
- Admin Panel: Administrators can manage users, listings, and handle disputes or quality control to maintain platform reliability.
Database Structure
The MyCollegeExchange database is structured to efficiently store and retrieve data. The selling table is joined with the books and members tables using SQL JOIN statements to generate information about who is selling what, when, and where. The books table uses an auto-incrementing Primary Key that is referenced by the selling table.
Installation and Deployment
The MyCollegeExchange website can be easily deployed in a new setting by creating the necessary SQL database based on variables set in a settings file that is called during installation.
Form Validation and Updating the Database
The Post a Book form on MyCollegeExchange uses JavaScript functions for validation. When a user posts a book using the form, the selling table in the MyCollegeExchange database is updated using PHP statements like mysql_connect, mysql_select_db, mysql_query, and mysqli_query.
Normalization
The MyCollegeExchange database has been normalized to the 3rd Normal Form, ensuring data integrity and reducing redundancy.
Line Validation
The registration, posting, and management forms on MyCollegeExchange have automatic line validation as the user progresses through the form.
MyCollegeExchange represents a practical example of how core web technologies can be used to solve real-world marketplace challenges in the education sector. Its user-friendly design and focus on textbook exchange make it an invaluable resource for college students.
Technology plays a crucial role in the creation and functionality of MyCollegeExchange, an online marketplace designed specifically for college students. This innovative platform, built using core web technologies, is equipped with features like PHP for server-side scripting, JavaScript for enhancing user interface interactivity, HTML/CSS for structuring and styling pages, and SQL for managing the database.
