Abstract :
We present a data model for movies and movie databases. A movie is considered to be a 2D semi-algebraic figure that can change in time. We give a number of computability results concerning movies: it can be decided whether a frame of a movie is only a topologically transformation of another frame; a movie has a finite number of scenes and cuts and these can be effectively computed. Based on these computability results we define an SQL-like query language for movie databases. This query language supports most movie editing operations like cutting, pasting and selection of scenes
