Episode 16 — Essential Terms: Plain-Language Glossary for Fast Recall and Clear Definitions
This episode builds a high-utility glossary for the Data+ DA0-002 exam by turning frequently tested terms into short, accurate explanations you can repeat under pressure. You will clarify foundational vocabulary that appears across every domain, including dataset, record, field, value, and the difference between a metric and a KPI. You will also connect structural terms like schema, table, view, and index to what they actually change in a data workflow, so you can recognize what a question is really describing. The focus stays on precision without jargon: primary key and foreign key become tools for keeping relationships consistent, metadata becomes “data about the data,” and lineage becomes the traceable path from source through transformations to the final report. By the end of the first half, you should be able to hear a prompt and immediately translate its terminology into the practical implications for analysis, reporting, and governance.
You will apply the glossary to short scenarios that mirror common exam patterns, where terms sound familiar but the meaning shifts depending on context. For example, you will practice distinguishing missing values from zeros, a baseline from a target, and an identifier from a numeric measure you should aggregate. You will also cover confusion traps that lead to wrong answers, such as mixing up “validation” with “verification,” or treating “source of truth” as a tool instead of a governance decision. Troubleshooting guidance focuses on what to do when two terms seem interchangeable: look for what action the term enables, what artifact it produces, and what risk it mitigates.
