Merge Purge Software

What is Merge Purge Software?

Merge purge is the process of combining two or more lists or files, identifying and/or combining duplicates, and eliminating (purging) unwanted records. Through phonetic and fuzzy matching algorithms, human errors such as typos are located and removed from data. The task of merge purging a database can be expensive and time-consuming, but with data quality tools like merge purge software, cleaning up dirty data is easier, faster, and more accurate than ever before.

GetTrialMerge Purge Best Practices

Understanding best practices in the merge purge process is often the first step in achieving success with this data cleansing process. One of the first steps in the merge purge process is combining different databases with different sources (such as an SQL server, MySQL, Excel, ODBC). DataMatch will import, combine, and export to the most common database formats. DataMatch will automap similar fields from different data sources together. Here are a few other best practices for merge purging data:

Run DME Agent     Fuzzy logic identification of percent matches between records and setting minimum percent match thresholds by field

Run DME Agent     Acronym identification for matching

Run DME Agent     Cleaning and standardizing data prior to matching (street to street, eliminating unnecessary syntax in phone numbers, etc.)

Run DME Agent     Applying libraries for standardization, especially for first names (such as Jon, Jonathan, and John

The Importance of Data Survivorship for Successful Merge Purge

Survivorship is critical to a successful merge purge. While removing duplicate records it needs to be decided which piece of data should stay (survive) and which one should be deleted.


Here you have two examples of the same data, with small differences. A single master record must be chosen to maintain data quality. With DataMatch, you can select which field of data survives, which field to merge on (in our example, it would be the customer number) and in which order (ascending or descending).

While standard merge purge software can remove important business data, DataMatch will retain and keep all pieces of information from the same master record — in a new data field.

All of the alternate information is captured in a brand new field, so the user has the benefit of a single master record without data loss. DataMatch never deletes any information from the source files; all information is kept temporarily in memory, so the user can test various merge purge settings. The final result would look like this:
