👉 Subduplicate is a term used in computer science and network theory, specifically in the area of domain-driven design (DDD). It refers to a duplicate of another object or data structure. In DDD, if you have an object named "Product" and another object called "Category", then any duplication would be through a subobject called "Subcategory". This is similar to how a product could have multiple categories in the same way that it has multiple products in the same category.
