1. Business Glossary beginner

    A 60-person company is told it needs a business glossary. Twelve people work with data and there are about 25 terms that anyone argues about. A glossary tool costs a subscription and a week of setup. What does the tool buy over one spreadsheet with a named owner, and when does the spreadsheet win?

  2. Data Access Models beginner Multiple choice

    An analyst can query the customer table. A regulator asks whether she was allowed to use it for the marketing model she built. Role-based access answers one of those questions and not the other. What is the difference between role-, attribute- and purpose-based access, and what does purpose add?

    A supplier table has 12% of rows with a blank tax identifier and 3% where the identifier is present but does not match the registry. Both are called data quality issues in the same report. Why does separating them change who is asked to fix them?

  6. Reference Data beginner

    An order total is stored as the integer 1000 alongside a currency code. In USD that is ten dollars. The same integer means one thousand yen in JPY and one dinar in KWD. A report sums the column across currencies and the total looks plausible. Why is this a reference-data problem rather than a bug in the report?
