This paper integrates diverse literature on natural language interfaces to databases, most of which emphasize technical issues. It formalizes one of the only categorizations of interfaces proposed in the literature. It also suggest how these systems may impact organizational activities, information systems usage, and decision makers' performance. A survey of information systems professionals regarding the use, role, importance, and perceptions about natural language interfaces is reported. The findings may be specially useful for developing implementation strategies for natural language based systems and further research in this area.
