Comments Above tests were completed on 15 different product comparisons with university, government, and private companies (80K to 8M records). This includes the effect of false positives. Need multi-threaded. in memory, no-SQL processing to optimize for speed and accuracy. Speed is important, the more match iterations you can run, the more accurate your results will be. Includes base license costs. 2014 prices or later, in-house, includes salary + benefits. Note in-house implementations had a 10% chance of losing in-house personnel, so over 5 years half of the in-house implementations had lost the core member who ran and understood the matching program. A metric for ease of use. This is the time to first result, not necessarily full cleansing.

What is Data Deduplication?

Data deduplication is the process of data removing duplicate items from databases and lists either by matching records manually or using data matching algorithms to automatically detect duplicates. The purpose of deleting duplicate rows/records is to clean the underlying data set to achieve productivity improvements, save on duplicate mailings, and increase customer satisfaction. Manually deleting duplicates can be a time consuming and error prone task, which is why dedupe software is an essential tool for enterprise-wide data quality initiatives.

Not all duplicate removal tools are created equal though. Most dedupe software utilizes fuzzy matching algorithms that go beyond exact matching to deduplicate accurately, but the accuracy and speed of matches vary greatly. Connectivity is another key concern – with most data duplication software allowing you to integrate with only a few common databases or excel files, whereas you need to dedupe across dozens of disparate sources spread through the enterprise.

You need a better, modern approach to data deduplication.

You need Data Ladder.
