}}</ref> In a study of citation patterns for database publication venues, TODS had the highest long-term impact, as measured by the frequency of citations to its papers, among any of the venues studied; however, most of those citations were outside the two-year window in which the [[impact factor]] is conventionally measured. Although its short-term impact factor was the highest among the journals included in the study, it was lower than that of several database conferences.<ref>{{citation
