Identify and Eliminate Duplicates Fast

On average, a database contains 8-10% duplicate records. These duplicates result in waste and inefficiencies and cloud your ability to get a single, accurate view of the customer.

Melissa is the most powerful and accurate matching and deduping solution on the market to combat the problem of duplicate records. What sets it apart from the rest is its intelligent parsing capability to understand and parse the various components of domestic and international addresses. By combining deep domain knowledge of international address formats and advanced fuzzy matching techniques, MatchUp gives you the ability to identify and merge/purge even the most difficult-to-spot duplicate records.

  • Eliminate clutter and duplicates that prevent a clear view of your customers
  • Increase the accuracy of your database – saving you time and money
  • Reduce postage and mailing costs by eliminating duplicates using advanced matching technology

  • First Name
  • Middle Name
  • Last Name
  • Suffix
  • Gender
  • First/Nickname
  • Middle/Nickname
  • Department/Title
  • Company
  • Company Acronym
  • Street Number
  • Street Pre-Directional

Global Merge / Purge & Deduping

The World Edition of MatchUp supports 12 countries, including Canada, Germany, U.K., and Netherlands. MatchUp’s advanced deduping can see through diacritic equivalents to Latin characters and interpret keywords that are the same but spelled differently (i.e. Germany and DEU).

Unique Matching Scenarios

MatchUp has some unique attributes which can be employed to help identify duplicates in some interesting ways.

1. Survivorship for Golden Record Creation


Matchup can select the best elements from multiple records to survive consolidation, ideal for the creation of golden records for a single customer view. Available in Microsoft SQL Server Integration Services (SSIS) and Pentaho PDI.

2. Proximity Matching


MatchUp’s patented distance algorithm uses latitude-longitude coordinates and proximity thresholds to identify duplicate records that are geographically close together. For instance, using location attributes, MatchUp can detect matching records at different addresses (for example, a company with two different entrances) but within a specified distance to each other.

3. Householding


MatchUp can identify and consolidate records that are members of the same household to better understand customer relationships, lifecycle, and needs. You can also use MatchUp to bring together multiple business accounts into “corporate families” to build insight and better evaluate the total sales relationship. Householding can also be used to eliminate unnecessary multiple mailings to the same household to cut down on wasted print, production, and postage costs.

Three Ways to Dedupe Your Data

MatchUp offers three methods of operation (or ways to match records):

1. Read / Write Deduping


Compares records in one or more databases at once. Each unique group will have one record that receives an “output” status; the other matching records receive a “duplicate” status. Ideal for matching entire databases at one time.

2. Incremental Deduping


Enables real-time matching by comparing each record as it comes in (like from a web form or call center) against the existing master database. If the incoming record is not a duplicate, it can be added.

3. Hybrid Deduping


Provides a combination of the first two methods with the flexibility to customise the process to match an incoming record against a small cluster of potential matches. With hybrid deduping you can store the match keys in a proprietary manner. Ideal for real-time data entry or batch processing of entire lists.
