            Classification is a logical and unambiguous arrangement of products into product categories. These are built up so that both suppliers and clients can communicate with each other. Individual models consist of tree structures composed of groups, classes, properties, values and keywords. So far, their similarity ends. Some models fit for one type of business, others have relatively advanced categorization options, and others have shallow tree structures that are usually best suited for purchase but are no longer suitable for engineering departments.
