Relational Algebra Tuple relational calculus Domain relational calculus from CS 3480 at Purdue University Unary Relational Operations: SELECT The SELECT operation (denoted by σ (sigma)) is used to select a subset of the tuples from a relation based on a selection condition. Materials 1. Intersection, as above 2. Constants 2. It is derived from predicate calculus. ∃ there exists 5. To brieﬂy introduce the tuple and domain relational calculi 2. The relational calculus tells what to do but never explains how to do. In Domain Relational Calculus, a query is expressed as, Relational Calculus (RC) does not imply any connection with the branch of mathematics usually called ‘Calculus’; rather RC comes from the first order predicate calculus from the field of Logic. Tuple relational calculus is used for selecting those tuples that satisfy the given condition. Because the coverage of Tuple and Domain Relational Calculus (TRC and DRC, respectively) often occurs in the window of time between the time Homework #1 is assigned and Exam #1 is taken, students don’t have a chance to practice with one or both of these languages before being tested on it/them. Tuple Relational Calculus is a non-procedural and declarative query language. Both based on 1st order predicate calculus . The DBMS uses the relational algebra internally, but query languages (e.g., SQL) use concepts from the relational calculus Relational Calculus Comes in two flavors: Tuple relational calculus (TRC) and Domain relational calculus (DRC). 2, …, x. n)} • x.
