Databases Course - Database Normalization - Functional Dependencies | Database Tutorial 6b

In this lecture of the databases course we learn about functional dependencies. Functional dependencies play a major role in the database design theory. They form the basis of the Boyce-Codd normal form (BCNF) and the third normal form (3NF). Functional dependencies are like partial keys, they determine some attributes of the relation not necessarily all of them. This is the databases online course given at the Vrije Universiteit Amsterdam by Jörg Endrullis. The course objective is to obtain a good understanding of relational database systems from the user perspective. This includes the ability to develop conceptual database models, as well as key concepts and skills in relational database theory and practice. Among others, we treat in this course the following subjects: (a) entity–relationship diagrams for the design of database schemata, (b) the relational database model and integrity constraints, (c) SQL (structured query language) for retrieving information from relational databases, (d) database normalisation and functiona dependencies (reasoning about good database design), (e) transactions and concurrency control. The slides are based on work by Peter Boncz and Torsten Grust.
