Self-service cohort selection for large-scale observational studies

A system, comprising:

• at least one data processor;
• and
• at least one memory storing instructions, which when executed by the at least one data processor, result in operations comprising:
• receiving, from a first client device, a first user input specifying one or more cohort selection criteria;
• generating, based at least on the one or more cohort selection criteria, a script for accessing a first data store storing a first dataset;
• executing the script to retrieve, from the first dataset in the first data store, a first subset of data;
• generating, for storage at a second data store, a second dataset corresponding to the first subset of data retrieved from the first data store;
• and
• generating, for display at the first client device, a visual representation of at least a portion of the second dataset.

A non-transitory computer readable medium storing instructions, which when executed by at least one data processor, result in operations comprising:

• receiving, from a first client device, a first user input specifying one or more cohort selection criteria;
• generating, based at least on the one or more cohort selection criteria, a script for accessing a first data store storing a first dataset;
• executing the script to retrieve, from the first dataset in the first data store, a first subset of data;
• generating, for storage at a second data store, a second dataset corresponding to the first subset of data retrieved from the first data store;
• and
• generating, for display at the first client device, a visual representation of at least a portion of the second dataset.
