Their use in primary schools allows pupils to have " concrete " yet full programming experiences at the age in which Piaget situates the concrete operational stage of cognitive development. Indeed, for their first robotic activities, pupils think of paths where the robot moves forward,(More)
ABsrRAcT The CODASYL database (db) statements m an apph-cation program can have one or more different semantics associated with It, dependmg on the path through which the execution reaches that statement This makes the CODASYL operations m a db program context dependent The previous works on the conversion of db programs from the CODASYL record at a time(More)
The conversion of database application programs is investigated when migration is required from a system with navigation (CODASYL-like) db interface to a system with specification db interface but the database semantics is not changed. We propose an analysis technique of the source program which heavily relies on program control flow. When the program(More)
