Practice questions

1 of 24Practice questions for this set
Based on the scenario described, a Medical Database supports population health reports for administrators. Instead of scanning every patient's full chart, the system abstracts each patient into a small "risk profile" with fields: ageGroup, chronicConditionCount, and recentHospitalVisits. An algorithm groups patients by ageGroup and computes average chronicConditionCount to identify which groups need additional resources. Pseudocode: 
profiles <- MAP(Patients, MAKE_RISK_PROFILE)
groups <- GROUP_BY(profiles, key = ageGroup)
report <- MAP(groups, AVG(chronicConditionCount))
Considering the example provided, identify the process that uses abstraction to convert raw data into actionable insights.
