US Patent 7693740 Dynamic selection of complementary inbound marketing offers

A database system and method comparing marketing events to marketing offers for offering to a candidate. The database system comprises a first database structure storing a first list of candidates, a second database structure storing a second list identifying marketing offers, a third database structure storing a third list identifying optimized marketing events for a first candidate from the first list, and a database manager software application stored on a computer readable medium. The database manager software application compares each of the optimized marketing events from the third list to each of the marketing offers from said second list in response to an inbound communication from the first candidate. The database manager software application extracts a first group of marketing offers from the second list. Each marketing offer from the first group comprises a same classification as any of the optimized marketing events from the third list.
