Database Processing and Application Software
Database Processing
Relational Database Management System (RDBMS): A relational database, such as MySQL, PostgreSQL, or Microsoft SQL Server, would be ideal for managing the entities and their relationships.
CRUD Operations: The system will require Create, Read, Update, and Delete operations to manage customers, jewelry pieces, orders, and customizations.
Transaction Management: To ensure data integrity, particularly for order processing and payment transactions.
Search and Filtering: Customers should be able to search for jewelry pieces by type, material, price range, etc.
Reporting: Generate reports on sales, customer orders, popular items, etc.
Application Software
Web Application: A user-friendly web application for customers to browse jewelry pieces, place orders, and request customizations. Technologies could include HTML, CSS, JavaScript, React.js for the front-end, and Node.js or Django for the back-end.
Inventory Management System: To keep track of available materials and manage inventory levels for 3D printing supplies.
Customer Relationship Management (CRM): To manage customer interactions, track order history, and handle customer support.
Design Software Integration: Integration with 3D design software (e.g., Blender, Tinkercad) to handle custom design requests and process 3D models.
