Relational Calculus

Lecture Discrete mathematics: Chapter 1.1 helps you to explore concepts in discrete mathematics using in computer systems. By following the book "Discrete Mathematics and Its Applications," Seventh Edition, by Kenneth H. Rosen, an introduction to the mathematical structures and concepts used in computing: sets, mathematical induction, ordered sets, Boolean algebras, predicate calculus, graphs, trees and relations will be presented in the course. Please refer to the detailed lecture content!

In this chapter, we start by presenting the relational algebra, which forms the basis of the widely used SQL query language. We then cover the tuple relational calculus and the domain relational calculus, which are declarative query languages based on mathematical logic.

Chapter 8: First-order logic. The main contents of this chapter include all of the following: First-order logic: objects and relations are semantic primitives; syntax: constants, functions, predicates, equality, quantifiers; Increased expressive power: sufficient to define wumpus world; Situation calculus: conventions for describing actions and change in FOL; situation calculus: can formulate planning as inference on a situation calculus KB.

The system is constructed in a lean deduction style and it has been inspired to some extent by a sequential reasoner leanCoP, implemented in Prolog. Our reasoner has a form of a relational program in the Oz language. In this programming model, a computational strategy is a parameter of a program having a form of a special object called a search engine.
