Press on the Resource Catalog icon, drag to ItemVariant and release your button. Move the mouse pointer over the Order entity. As each Order can have multiple ItemVariant, and each ItemVariant can be involved in multiple Order, therefore it is a many-to-many relationship. We should relate the Order with ItemVariant instead of Item since ItemVariant is the entity storing the actual item. Finally, we have to store the items purchased on each order.Repeat the steps above to create the ERD as below.Right-click on ItemVariant entity and select New Column from popup menu, then enter the following columns.Select One-to-Many Relationship -> Entity in Resource Catalog. Press on the Resource Catalog icon at the top right of shape and drag it out. Move the mouse pointer over the Item entity.
