From the publisher:

Understand the language and vocabulary of Data Architecture. The Data Architecture field is rife with terms that have become “fashionable”. Some of the terms began with very specific, specialized, meanings – but as their use spread, they lost the precision of their technical definitions and become, well, “buzzwords”. A buzzword is “a word or expression from a particular subject area that has become fashionable because it has been used a lot”. Compliance is “the obeying of an accepted principle or instruction that states the way things are or should be done.” The assignment is to take buzzwords

Highlights

  • Buzzwords are terms that lost their definitions — Hay's diagnosis is that words like "data lake", "metadata", and "ontology" began precise and eroded through fashion; restoring the definition is an act of engineering, because you cannot generate from an ambiguous term.
  • Vocabulary discipline is architecture work — treating the language of data architecture as something to be modeled, not just used, elevates definitions to first-class artifacts — the same move a concept-library makes for a content system.
  • Layers of abstraction deserve distinct words — Hay carefully separates business concepts, logical data structures, and physical implementations; collapsing these vocabularies into one is where most architecture conversations (and models) go wrong.
  • A term's meaning lives in its relationships — definitions gain precision when anchored to neighboring concepts rather than written in isolation; a validation of typed concept-to-concept links over loose tag clouds.
  • Fashion cycles churn the words, not the fundamentals — each hype wave rebrands old ideas with new labels; knowing the stable concept under the shifting vocabulary is what lets a modeler survive platform and terminology churn alike.
  • Shared language precedes shared models — before two parties can agree on a data model they must agree on what the words in it mean; semantics-first is the entry condition for any model-driven pipeline.
