About This Architecture

Digital product marketplace ERD in Chen notation models a complete e-commerce ecosystem with users, products, orders, licenses, and support workflows. The schema connects USER entities to PRODUCT through ORDER and ORDERITEM, with PRODUCTIMAGE, PRODUCTCOMPATIBILITY, and PRODUCTREVIEW enriching product data, while LICENSE and SUPPORTTICKET manage post-purchase customer relationships. This normalized structure supports multi-tenant product distribution, payment tracking via Snap integration, and customer support workflows with attachments. Fork this diagram on Diagrams.so to customize entities, add payment provider details, or extend support ticket workflows for your marketplace. The Chen notation clearly shows cardinality and relationships, making it ideal for SQL schema generation or NoSQL document design.
