Varieties play a significant role for databases: they are related with the idea of data type, one of which is of importance in programming theory.作者: IVORY 時間: 2025-3-27 02:21 作者: granite 時間: 2025-3-27 06:02 作者: Affection 時間: 2025-3-27 11:18 作者: Ccu106 時間: 2025-3-27 17:10
Connections With Model Theoryer, by the corresponding Halmos algebra. The present chapter contains some relevant information.

Algebraic Model of a Databasealgebraic structure. For example, the algebraic model of an automaton is already well-known, and here the algebraic model of database is created.

Halmos Algebras and Predicate Calculustion of predicate calculus can also be achieved on the basis of Tarski’s cylindric algebras which were introduced a bit earlier. One more approach to algebraization of predicate calculus is based on categorical logic and was discovered in early 60-ies. This approach will be discussed in Chapter 11.作者: 缺陷 時間: 2025-3-28 20:33 作者: fructose 時間: 2025-3-29 00:07
Algebraic Model of a Databaseions of isomorphism and equivalence of two databases, one can also consider the structure of a database, its subbases, homomorphisms and automorphisms, i.e., the symmetry of databases, and so on. The contents of the previous chapters provide the necessary background to the design of the database model considered here.作者: 牌帶來 時間: 2025-3-29 03:09
