What is the best reason for capturing synonyms in a data repository?

Synonyms are good for indexing or for uncontrolled vocabularies

You should capture all synonyms in one place so that Data Governance can decide on the best name for an element

Synonyms are useful in discovering relationships between data elements

Not all parts of an organization may name a field exactly the same, and the synonym will aid in data searches

Without synonyms, you may not realize that two fields are the same
