International audienceThis chapter presents some noteworthy works which show the links between Databases and Artificial Intelligence. More precisely, after an introduction, Sect. 2 presents the seminal work on "logic and databases" which opened a wide research field at the intersection of databases and artificial intelligence. The main results concern the use of logic for database modeling.
