===== Introduction =====

ACHILLES is a platform which enables the characterization, quality assessment and visualization of observational health databases. ACHILLES provides users with an interactive, exploratory framework to assess patient demographics, the prevalence of conditions, drugs and procedures, and to evaluate the distribution of values for clinical observations.

==== Scope and purpose ====

ACHILLES is intended to be implemented by organizations that have patient-level observational health databases available in their local environment.  By itself, ACHILLES does not perform study-specific analysis, but can assist exploring the contents of a CDM database to determine whether data exists that can support a study.

ACHILLES consists of:

  - Pre-computations (for database characterization)
  - Achilles Heel for data quality
  - Index generation for better performance with Atlas Data Sources
