How to Choose the Right Real World Data
We separate options in real world data work by how reliably they connect provenance-ready data sources and produce queryable, documented outputs. The biggest difference shows up in automation depth, RBAC with audit log, and data model fit for your analysis workflow.
Source coverage for real world data
Why it matters
Source coverage determines whether your cohorts reflect the real world settings you care about, not just what happens to be available. For real world data, gaps force rewrites later when your use case is ready to run.
How to check
Ask for the included source catalog and filter it by your target domain (claims-like, encounters-like, lab-like, or provider-like). Then demo a single end-to-end workflow: pick one source, run one extraction, and confirm fields and time granularity match what you need.
Data model mapping and schema control
Why it matters
Data model mapping and schema control decide whether your team can move from extraction to analysis without fragile reformatting. With real world data, small schema mismatches can silently change cohort logic.
How to check
Request a sample export for one cohort definition and review the schema: keys, dates, and join-ready identifiers. Ask how mappings are configured and versioned, and whether the system outputs a documented schema you can reference in analysis notes.
API and automation for repeatable extracts
Why it matters
API and automation for repeatable extracts reduce the drift that happens when analysts rebuild queries by hand. For real world data, repeatability matters when you iterate cohort logic and re-run experiments.
How to check
In the demo, request a way to trigger an extract from the API and to parameterize time windows and cohort criteria. Confirm whether outputs can be re-run identically and whether the workflow emits a machine-readable job history.
RBAC and audit log for datasets
Why it matters
RBAC and audit log for datasets determine who can provision or re-use real world data outputs, and whether you can explain access later. This is often required when multiple analysts share the same data assets.
How to check
Ask for roles and permissions that separate browsing from extraction and downloading. Then show an audit log entry stream for a sample user: dataset access, extract runs, and export actions.
Documentation of source provenance and lineage
Why it matters
Documentation of source provenance and lineage helps your team validate that an output truly reflects the underlying real world data choices. Without it, you spend time reverse-engineering transformations.
How to check
Pick one field in the demo output and ask where it comes from, including transformation notes. Check whether the system can show a provenance summary per dataset and per extract run, not just generic documentation.
Data quality checks in the extract workflow
Why it matters
Data quality checks in the extract workflow catch missingness, date issues, and join failures before they alter cohort results. In real world data, early detection prevents expensive rework and inconsistent findings.
How to check
Request a demo run that includes quality metrics: record counts by day, null rates for key fields, and missing join rate. Ask whether these checks block exports or at least annotate the output with run-specific findings.
Red flags
- Outputs lack a queryable schema or documented field meanings.
- API demos can’t reproduce the same extract parameters and results.
- Audit history is limited to logins, not dataset access and exports.
Fit by situation
- If your team needs repeatable cohort runs for quarterly updates, prioritize API and automation for repeatable extracts.
- If you must defend field definitions during analysis reviews, prioritize documentation of source provenance and lineage.
- If multiple analysts share datasets with different access needs, prioritize RBAC and audit log for datasets.
