Supporting Tables These tables normalize your data to prevent redundancy. - Categories Table | Field Name | Data Type | Suggested Length | |---|---|---| | Category_ID | INT | Primary Key | | Category_Name | VARCHAR | 50 | - Suppliers Table | Field Name | Data Type | Suggested Length | |---|---|---| | Supplier_ID | INT | Primary Key | | Name | VARCHAR | 100 | | Contact_Info | VARCHAR | 255 | - Transactions Table | Field Name | Data Type | Suggested Length / Format | |---|---|---| | Transaction_ID | BIGINT | Primary Key | | Item_ID | INT | Foreign Key | | Type | ENUM | 'In', 'Out', 'Adjustment' | | Quantity_Change | INT | 11 | | Transaction_Date | DATETIME | N/A | - Users Table | Field Name | Data Type | Suggested Length / Format | |---|---|---| | User_ID | INT | Primary Key | | Username | VARCHAR | 50 | | Password_Hash | VARCHAR | 255 | | Role | ENUM | 'Admin', 'Staff', 'Viewer' | System Functionality (HTML, CSS, JS, PHP) These are the features the code will enable HTML & CSS (Presentation) Interface Layout: Create clear, organized pages for viewing, adding, editing, and reportingon inventory. Forms: Input forms for adding new items, recording sales/purchases, and logging in. Data Display: Tables to show the current inventory with sorting and filtering options. Styling: Use CSS ( and potentially a framework like Bootstrap) for a user-friendly and responsive design. Javascript (Client-Side Logic) Data Validation: Ensure users enter current information before it to PHP. Dynamic UI: add interactive elements like searching, sorting table without a full page reload, and showing/hiding forms fields. AJAX: Use JS (fetch or XMLHttpRequest) to communicate with your PHP scripts to update the database without reloading the whole page. PHP (Server-Side Logic) Database Connection: Connect to your database (using MySQL or PDO is recommended). CRUD Operations: PHP scripts handle the core logic: - Create (adding new items) - Read (Fetch and Display inventory list) - Update (Modify information) - Delete (Deleting records) Here are the html/scripts in an txt and php extension. ——————————————————- https://convertowordpress.com/ctw/databaseStructure.txt https://convertowordpress.com/ctw/hashPass.php ——————————————————- Check out the PHP manual that is available online: https://www.php.net/docs.php If you want a developer to create your web design project.
