User Authentication: Validate user credentials (username/password) against a database. Generate and store a session token upon successful authentication to maintain user's login state. Authorization: Define user roles (e.g., admin, manager, staff) and permissions. Check user's role and permissions before allowing access to specific functionalities. Dashboard Management: Retrieve relevant data to display on the dashboard (e.g., total sales, recent orders, reservations). Allow admins to customize dashboard widgets and layouts. Implement CRUD (Create, Read, Update, Delete) operations for dashboard components. Menu Management: Fetch menu items from the database. Provide CRUD functionalities to add, edit, or delete menu items. Allow categorization of menu items (e.g., appetizers, main course, desserts). Enable admins to set prices, descriptions, and availability for menu items. Reservation Management: Display existing reservations with details (e.g., date, time, number of guests). Implement CRUD operations for reservations. Allow admins to confirm, modify, or cancel reservations. Provide a calendar view for managing reservations by date. Order Management: Show current orders with details (e.g., items, quantity, total price). Enable CRUD operations for orders (mainly for administrative purposes like refunding or canceling orders). Allow filtering orders by status (e.g., pending, processing, completed). Integrate with a payment system to process orders. Data Persistence: Use a database to store and retrieve data (e.g., MySQL, PostgreSQL, MongoDB). Ensure data consistency and integrity through proper transaction handling. Logging and Monitoring: Log important events and actions performed by admins for auditing purposes. Implement monitoring functionalities to track system performance and user activities. Security Measures: Sanitize user inputs to prevent SQL injection, XSS (Cross-Site Scripting), and other security vulnerabilities. Encrypt sensitive data like passwords and session tokens. Implement rate limiting and CAPTCHA to prevent brute force attacks. User Interface: Design an intuitive and user-friendly interface for easy navigation and interaction. Use responsive design to ensure compatibility across various devices and screen sizes. create a flowchart for given information
