2. A method according to claim 1 , wherein determining the compression ratio includes generating the first query result decision diagram based on the first query instruction to facilitate determining the first compression value for a first query result decision diagram and wherein the compressed query result set is compressed using a technique that differs from the use of a decision diagram.
1. A method comprising: receiving a first query instruction; in response to receiving the first query instruction, determining a compression ratio of a first compression value for a first query result decision diagram and a second compression value for a compressed query result set, the first compression value being indicative of a data size of the first query result decision diagram and the second compression value being indicative of the data size of the compressed query result set; comparing the compression ratio to a threshold ratio; and causing transmission of the first query result decision diagram or causing transmission of the compressed query result set based upon a result of the comparison of the compression ratio to the threshold ratio.
