What is a data dedupe software
and why do you need it?

Over 90% of databases consist of duplicate customer data that are obsolete and incomplete. Yet companies are unable to tackle duplicate data efficiently because the  data dedupe process is expensive, complex and resource-intensive. That’s where a dedupe software like WinPure can help. Built with powerful data match algorithms, the software can identify non-exact matches (for example, Sander vs Sandler) within just minutes and help both business and tech users to resolve duplicate data challenges without requiring any additional resource. Moreover, with a no-code approach, users do not need to know code to dedupe data. Developers and data analysts can identify duplicates with 97% accuracy, without having to build dedupe algorithms from scratch. It’s a win-win for everyone!

Top data dedupe tool features unique to WinPure 

Dedupe tool with built-in data profiling capabilities

A key part of the data dedupe process is identifying and fixing common data errors. Issues like transposition errors, accidental text and number entries in the data field, and missing or null values affect the accuracy of a deduplication process. WinPure’s data profiling allows users to do an in-depth review before initiating the dedupe process.

You can also use a built-in word library to create custom cleansing definitions (such as instructing the software to ignore Ltd or Limited).
