The vocabulary (formally known as a Controlled Vocabulary), or Business Vocabulary, is often the most over looked information artifact that is actually critical to bridge the gap between the Profit Centers (often termed "The Business") and IT. Before attempting to do a more in depth model having a commonly understood language is key fact to the success of other Information models.

The vocabulary normally evolves from a simple flat glossary structure, through a Taxonomy structure, and finally ending up as a Thesaurus. However it should always be remembered that it should be "fit for purpose", and no more complicated than needed. As such in certain cases it may very well only merit the vocabulary being stored in a flat glossary, while more sophisticated uses may require a fully fledged thesaurus.
