The most frequently mentioned domains within Master Data Management (MDM) are customer, product and location. Data quality is a core discipline when working with MDM. In data quality we talk about different dimensions as uniqueness, relevance, completeness, timeliness, precision, conformity and consistency.
While these data quality dimensions apply to all domains of MDM, some different dimensions apply a bit more to one of the domains or the intersections of the domains.
Below is a figure with an attempt to illustrate where the dimensions belong the most:
Uniqueness is the most addressed data quality dimension when it comes to customer master data. Customer master data are often marred by duplicates, meaning two or more database rows describing the same real world entity. There are several remedies around to cure that pain. These remedies are explored in the post The Good, Better and Best Way of Avoiding Duplicates.
With product master data, uniqueness is a less frequent issue. However, completeness is often a big pain. One reason is that completeness means different requirements for different categories of products as explained in the post Hierarchical Completeness within Product Information Management.
When working with location master data consistency can be a challenge. Addressing, so to speak, the different postal address formats around the world is certainly not a walkover. Even google maps does not have all the right answers as told in the post Sometimes Big Brother is Confused.
In the intersection between the location domain and the customer domain the data quality dimension called precision can be hard to manage as reported in the post A Universal Challenge. What is relevant to know about your customers and what is relevant to tell about your products are essential questions in the intersection of the customer and product master data domains.
Conformity of product data is related to locations. Take unit measurement. In the United States the length of a small thing will be in inches. In most of the rest of the world it will be in centimetres. In the UK you can never know.
Timeliness is the everlasting data quality dimension all over.
