What kind of data do I save in a PIM-system? The figure below shows the various types of product data. The darker types belong to the basic data or stem data of the products. The lighter types, depending on the functionality of the PIM-system and surrounding systems, will be saved and maintained in the PIM-system. Once the data gains a transactional nature, they will not be maintained in the PIM-system. This also applies to analytic data, which is generally saved in data warehouses. These are build up of transactional data.
