Master Index Match Engine Overview

The Master Index Match Engine is the standard match engine designed to work with the master index applications created by Oracle Java CAPS Master Index. The match engine can also be called from other applications. It is highly configurable in the Oracle Java CAPS Master Index environment and can be used to match on various types of data. The match engine is highly configurable in the Oracle Java CAPS Master Index environment and can be used to match various types of data. The Master Index Match Engine works in conjunction with the Master Index Standardization Engine to improve the quality of your data.

The following topics provide information about matching concepts, the match process, and how the Master Index Match Engine matches data.
