Duplicate

In master data management a duplicate group is one that has two or more database rows representing the same real-world entity.

For example, the two names “Bob Hope” and “Robert Hope” residing on the same address may be identified as the same real-world person.

Master data management solutions aim to establish and maintain a single view of business partners . This discipline is called identity resolution.

In entity resolution we may also find, for example, two product master data rows describing the same real-world product. This is used as part of improving product data quality.
