However, throughout the entire production process, from the purchase of raw materials to the sale of products, countless data are generated that are somehow interrelated. It is therefore not without reason that a central demand in the context of digitisation is the Single Soruce of Truth. This concept of data storage enables all departments to access a central data source which is constantly maintained and therefore only contains consistent and redundancy-free data. This data storage prevents errors due to the use of different data bases, but above all it makes certain evaluations possible. Only in this way can the profit of a company be consistently depicted over the entire value-added chain and across all levels. It is not without reason that it is considered indispensable to lead Industry 4.0 projects to success.
