Chris Date responded with the following design for the ratlets problem: CREATE TABLE Litters (litter_id INTEGER NOT NULL PRIMARY KEY, ratlet_tally INTEGER NOT NULL); CREATE TABLE Ratlets (ratlet_id CHAR(15) NOT NULL PRIMARY KEY, litter_id INTEGER NOT NULL REFERENCES Litters(litter_id)); When there’s a new litter, we make the obvious entry in litters. When an individual ratlet becomes “interesting” (unlike Reinke, Date did not like the word “distinguishable” because distinguishability presupposes identity), we make the obvious entry in ratlets.

I asked him to what extent the product - 30 - supported the existential quantifier. ” So right there, I knew that he didn’t know a damn thing about predicate logic. DBMS: I guess for him it wasn’t an an [sic] intuitive leap to connect predicate logic to the management of data. But you made that leap somehow? CODD: I felt that it was a natural thing to do. I did my studies in logic and mathematics and it occurred to me as a natural thing for queries. Then it occurred to me—and I can’t say why ideas occurred to me, but they keep doing so, and I’m not short of them even now, I can tell you—why limit it to queries?

While there are many exotic hashing functions, the major algorithms fall into four types: 1. Digit selection: Pick a subset of the bits, characters, or digits that make up the input value. That is what the telephone number trick we just discussed does. 2. Division: The input is treated as a number that is divided by a second number, and the remainder is used as the hash. That is, Hash(x) = MOD (x, m). It is important that m be a prime number for reasons we will discuss later. 3. Multiplication: The input is treated as a number that is multiplied by a second number, and then a subset of digits (usually in the middle of the result) is used as the hash.
