The not same as is a relationship that helps you identity the following types of terms:

Terms that have a similar name but have different meanings. Link to business terms that have the same name as the current business term but are semantically different. For example, in the manufacturing glossary, "shuttle" can be used to denote weaving or to denote a transportation vehicle.
Terms that business users might use to denote the current term, but are not an accurate representation of the current term. For example, the term "portfolio" is not the same as "stocks."

A parent-child relationship is a relationship that helps you to link business terms to other terms that define high level concepts. The business term that you are defining might use the high level concept that is available in a parent term. The child business term can derive information based on the concepts in the parent business term. Link the parent business term when you define the child business term. You can view the child term in the

children

property when you open the parent term.

For example, "simple mortgage" and "reverse mortgage" are child terms to the parent term "mortgage."

The contains property helps you to identify other business terms used to implement the concept or practice in the current business term.

For example, a bank check contains a Magnetic Ink Character Recognition (MICR) number. If the current business term is "check," use the contains relationship to link to the business term "Magnetic ink character recognition (MICR) number."

The calculated from property helps you to identify business terms from which you can calculated the value of the current business term.

For example, the value of the term "gross profit" is calculated from the value of the business term "revenue."
