| Abstract: | Two phenomena regarding succintness in dependency systems are given. In the first, a minimum system of FDs can be induced by a much smaller (log size) system of FDs over a larger set of attributes. In the second, a minimum system of FDs can be induced by a much smaller (again log size) system of FDs and MVDs over the same set of attributes. |
