They even handle significantly more than 4 billion relationship questionnaires, with more than 25 terabytes of information.
• Compatibility matching system (CMS versions) — eHarmony’s “secret sauce, ” composed of a rather sophisticated three-tier procedure:
  1. Compatibility matching models – identify potential matches predicated on a customer’s core compatibility, produced from 29 measurements of character and psychology faculties and on the basis of the user group of choices. It really is a two-step procedure to help a complicated bidirectional system to ensure individual choices are met both in guidelines.

Just those prospects whom pass the limit set because of the CMS models are retained and placed as prospective matches that are compatible the customer. “
