Data Management & Integration Flashcards

What defines an event-based data model compared with a session-based model?

Answer: Every interaction is recorded as an event with parameters

Event-based models treat each interaction as an event, with sessions derived from them.

A user-scoped custom dimension is applied to which data?

Answer: All of that user's events until the value changes

User scope persists the value across the user's sessions and events.

What happens when a dimension has very high cardinality in a report?

Answer: Values may be grouped into an '(other)' row

Reports cap unique values and roll the excess into '(other)'.

Why might today's numbers in standard reports differ from later totals?

Answer: Processing latency means data can still be updating

Standard reports can take time to fully process incoming data.

What is a calculated metric?

Answer: A metric built from a formula using existing metrics

Calculated metrics combine existing metrics, such as revenue divided by sessions.

What is a typical limitation of data blending in dashboards?

Answer: Blended sources must share a join key, and some metrics can't be aggregated reliably

Blends rely on a common join key and may restrict metric behavior.

What does bot and spider filtering accomplish?

Answer: Excludes known automated traffic from reports

Bot filtering removes known non-human traffic to keep metrics accurate.
