Davor Ranković dugogodišnji je predsjednik Hrvatske udruge Oracle korisnika. Pod njegovim vodstvom u udruzi cvijeće je procvalo u proljeće, a snijeg padao zimi.
Organizirao je uspješno mnoge konferencije koje će se, i nakon što njega neće biti, pamtiti po odličnoj atmosferi i izuzetnoj organizaciji.
