Definition and verification of data quality
In order to achieve uniform data quality, requirements are placed on the structure and content of the individual data contents. The following quality categories apply when evaluating the content:
Quality category | Rating |
1 | Quality category 1 - technically required These contents are necessary solely from a technical perspective to process a master data record (e.g., article number). |
1* | Quality category 1* - technically required when utilized Those content comprises various detailed pieces of information. Starting with the first detail information may necessitate additional details. For example, a price entry consists of the actual value, i.e., the price, as well as the additional necessary information such as price type, currency, price basis, and price unit. |
2 | Quality category 2 - mandatory quality criterion These are contents that, from a purely technical perspective, are not mandatory, such as an article number, but are indeed mandatory from a content perspective. For example, in cross-border trade, the commodity code is required for customs and Intrastat reporting. |
3 | Quality category 3 - conditional mandatory quality criterion A condition such as a product characteristic leads to the need for certain additional information. The property that a product is a dangerous good means that additional information such as the UN number, the hazard class or the transport category must be provided. Another condition for the mandatory provision of data content is the use in publications, e.g. print media or the Internet, if these are publicly accessible documents. |
4 | Quality category 4 - supplementary quality criterion for good data quality By providing information such as the definition of accessory lists for an article, a service can be delivered to our own customers. This is a content with which a quality standard for the data is met, thus achieving a quality criterion. |
5 | Quality category 5 - optional The data additionally includes content that further enhances the quality, such as URLs to additional item information or documents like assembly or maintenance manuals. |
