Match Segments is a term used in the field of computer science. It refers to the process of finding and connecting similar parts of two or more data sets. This process is often used to compare different versions of the same data set, or to compare different data sets to each other. Match Segments can also be used to identify patterns in data sets, or to identify relationships between different data sets. The term SETS (4 letters) is an acronym for Structured Equivalence Testing System, which is a type of software used to perform Match Segments.
