NORA is an acronym for Non-Obvious Relationship Awareness, a technology that mines data resources to determine the relationships between people. Non-Obvious Relationship Awareness was created by Systems Research and Development (SRD). SRD developed this technology for the Las Vegas gaming industry to help the casinos detect relationships between customers and parties named by the Nevada Gaming Control Board as excluded persons. SRD was acquired by IBM on January 7, 2005.[1]
