Yasushi Suzuki,Mohammad Dulal Miahe show that, if the data source is modeled as a single relation, an optimal plan can be found in a time linear in the number of functions in the source but, if the source is modeled as a number of relations that can be joined, finding the optimal plan is NP-hard.作者: hedonic 時(shí)間: 2025-3-25 23:52 作者: 神圣在玷污 時(shí)間: 2025-3-26 01:33
