Databases Course - Database Normalization - Canonical Sets of Functional Dependencies | Database Tutorial 6d

In this lecture of the databases course we learn how to compute a canonical (minimal) set of functional dependencies. In the database design process we are not interested in the (huge) set of all functional dependencies, but only in a small representative set that implies all other functional dependencies. We will see how to compute a minimal set of functional dependencies from a given set of functional dependencies. 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.
