Relational Model and Algebra - CMU Intro to Database Systems - 01

Learn the foundational concepts of the relational model and relational algebra in this 75-minute lecture from Carnegie Mellon University's Introduction to Database Systems course. Explore the mathematical foundations that underpin modern database systems, including the structure and properties of relations, keys, and constraints. Master relational algebra operations such as selection, projection, union, intersection, difference, and joins, understanding how these operations form the theoretical basis for database query languages. Examine real-world applications of relational model concepts and discover how relational algebra translates into practical database operations. Access comprehensive course materials including detailed slides and supplementary notes to reinforce your understanding of these fundamental database concepts taught by Professor Andy Pavlo.
