Matchcode Optimization:Advanced Component Types
Advanced Matchcode Data Type
Most matchcode component data types specify the format of the source data, and any advanced operations that need to be performed on that component are specified in its properties. There are three exceptions, which also require a unit range of variance that will still constitute a match:
- Date (days)
- Numeric (units)
- Proximity (miles)
A match if the distance between two records being matched is within the configured range.

|More Matches||Greater Accuracy|
Hybrid deduper, where a single incoming record can quickly be evaluated independently against each record in an existing large master database.
Small batch runs or larger batch runs when higher listed matchcode components have efficiently grouped records by clustering and therefore reduced the number of records that need to have the unit difference math performed.
Not Recommended For
Large or enterprise level batch runs. Since the proximity must be evaluated for each record comparison, throughput will be very slow. Each swapping attempt takes a late speed hit similar to when using a fuzzy algorithm.
