Must Know Cold & Must Distinguish

Must know cold

  • Data Architecture: identify enterprise data needs and design/maintain master blueprints to meet them.
  • Bridge: business strategy ↔ Data Architecture ↔ technology execution.
  • Three components: outcomes/artifacts; activities; behavior.
  • Four EA domains: Business, Data, Application, Technology.
  • Zachman: What, How, Where, Who, When, Why; ontology, not methodology.
  • Enterprise Data Architecture: EDM + Data Flow Design.
  • Vertical mapping: abstraction-level model lineage.
  • Horizontal mapping: same-level cross-model relationships.
  • Practice work streams: strategy; acceptance/culture; organization; working methods; results.
  • Roadmap: pragmatic roughly 3–5 year development path.
  • Implementation paths: buy, reuse, build.
  • Lifecycle: be able to classify the eight status terms, especially Preferred/Emerging/Containment/Retirement.
  • Architecture governance: oversee projects; manage designs/lifecycle/tools; define standards; create data artifacts.
  • Metrics: compliance; implementation trends; business value.

Must distinguish

A B Deciding clue
Data Architecture Data Modeling & Design enterprise blueprint/roadmap/alignment vs specific model/design execution
EDM Data Flow Design meaning/relationships vs movement/storage/transformation/context
Enterprise conceptual/logical Project logical/physical common enterprise semantics vs scoped/implementation-specific design
Vertical linkage Horizontal linkage across abstraction levels vs same-level peer models
Current state Target state what exists vs intended future
Target state Transition state destination vs intermediate migration condition
Framework Roadmap structure for thinking vs sequence for evolution
Zachman ontology Methodology classifies artifacts vs prescribes how to create them
Quality-oriented Innovation-oriented prevent deterioration/standardize vs transform/explore new opportunities
Preferred Emerging recommended now vs researched/piloted
Architecture governance Project execution set/oversee requirements vs implement solution
Compliance metric Implementation metric followed standards/process vs actual estate evolution
Implementation metric Business-value metric changed estate/reuse/retire vs improved enterprise outcome

Selective memorization

Memorize exactly: - definition, - three components, - four domains, - six Zachman interrogatives, - EDM vs flow, - vertical vs horizontal, - five work streams, - roadmap duration, - lifecycle labels, - four governance activities, - three metric families.

Understand rather than recite every figure example, risk wording, or diagram rule. The exam value is being able to recognize what those examples demonstrate.
