SNAP Query and Filters

SNAP supports exploratory querying through UI filters and query presets.

This page provides fake but realistic guidance for testing query behavior.

Query building blocks

• Dataset selection
• Dimension filters
• Metric choice
• Time range
• Aggregation level
• Sort and limit

Typical filter combinations

Regional trend analysis

• Theme: Jobs & Employment
• Geography: NUTS2
• Years: 2017-2025
• Metric: Employment rate

Skills gap screening

• Theme: Skills & Training
• Region: single country + comparator region
• Age group: 25-54
• Metric: Skill shortage proxy

Save and reuse queries

Users can save query presets:

• Name
• Description
• Parameter defaults
• Visibility (private/team)

Query performance notes

• Prefer narrower time ranges for interactive charts.
• Avoid requesting too many high-cardinality dimensions at once.
• Use aggregation before export when possible.

Simulated pseudo-query

SELECT region, year, employment_rate
FROM regional_employment
WHERE country IN ('EL', 'IT', 'ES')
  AND year BETWEEN 2018 AND 2025
ORDER BY year ASC

Debug checklist

• Changing one filter triggers one data refresh.
• Saved preset restores all filters and metric choice.
• Reset action returns to baseline state.

Frequent user confusion

• No data from incompatible filters.
• Comparing monthly and annual indicators in one chart.
• Applying country filter after region filter with mismatched scope.
