What are duplicates and how do they occur?
Duplicates are data records, mainly in address databases, which have different contents but represent one and the same person, company or institution. Finding and identifying or eliminating them is very time-consuming without the appropriate tools - especially if the database contains many addresses. 4-6% of addresses are usually duplicated in typical, well-maintained customer databases. The consequences are: Double costs for postage and printed matter, errors in the maintenance of customer data (one data record is updated, the duplicates are not) and, as a result, incorrect information to customers when they have queries about their master data.
Duplicates usually occur when new records are created by:
or when merging different databases or tables or comparing different address lists. The latter is very time-consuming and costly, especially for small and medium-sized companies, and also has a high error rate.
This is exactly where Nexo comes in 2023. The programme analyses all address data, eliminates duplicates, corrects e-mail addresses and postcodes and cleans selected data fields. In addition, different databases can be compared with each other.
