Inf. Process. Lett. H. hu Dedicated to Professor Bernhard Thalheim for his 60th birthday Abstract. A model of random databases is given, with arbitrary correlations among the data of one individual. This is given by a joint distribution function. The individuals are chosen independently, their number m is considered to be (approximately) known. The probability of the event that a given functional dependency A → b holds (A is a set of attributes, b is an attribute) is determined in a limiting sense.

Then maxk qk →0 k qk (12) implies 2 k qk k qk ) ( 2 → 0. (13) Proof. Use (11) of Lemma 2 with c(n) = maxk qk and s = 2 k qk ( k qk ) 2 ≤ k qk c(n) + 1 c2 (n) 2 k qk ) ( = c(n) + k qk k qk : c(n) k qk 2 shows that (12) really implies (13). Return to the proof of Theorem 2. Lemma 3 will be applied for the values p2κ (A) in place of qi . Condition (12) becomes exactly (8), therefore (13) gives ( 4 κ pκ (A) 2 2 κ pκ (A)) → 0. H. Katona Let us now give a lower estimate on p(α, ξb , I) using (ii) (that is (9)) p(α, ξb , I) = p2κ (A) − κ p2κ, (A, b) ≥ (1 − u) κ, κ p2κ (A).
