Sun Master Index provides the ability to use the standardization and match engines that best suit your indexing requirements. You can configure the master index application to use the Master Index Match Engine and the Master Index Standardization Engine, or you can configure the index to use a customized engine of your choice.
These engines perform two functions:
Standardize data to a common format
Calculate the likelihood that two objects match
The engines are called during match processing, when the master index application retrieves the best matches during a weighted search from the MIDM or when the master index application checks for duplicate records during an insert or update from the MIDM or an external system.
