The Ekiosk© and Operative Notes© data structures are maintained to "normalize" the data for both functionality and security. This creates relationships between tables, which all have distinct but limited data, and the combined tables create the complete data structure. This also has the benefit of the making the data not personally identifiable to improve security. In addition, unless the practice develops their own database of patients with name and passwords only, a mapped connection to an existing billing or EMR database has the advantage of utilizing native security features inherent in the mapped databases. The only connection of patients to their data is through table unique ID numbers.
