Yazılım geliştirebilmenin formal metodları o yazılım tanımlamasının geçerli­liğine bağlıdır. Böyle bir tanımlama genelde 'Z' gibi bir formal dilde ifade edilir. A n­cak, geçerli olması için, 'Z' tanımlaması test edilmeli, bunu yapabilmek için de ani­m asyon yapılabilecek ve icra edilebilecek bir forma transfer edilebilmelidir. 'Z' ta­nımlamalarının animasyonları için kullanılan dillerden birisi Prolog'dur. Bu makale­de 'Z' şemalarını Prolog'a çeviren teknikler açıklanmaktadır.Aym zamanda bu tür bir çevirmenin eksikleri ve belirsizlikleri üzerinde durulacaktır

ANIMATION OF Z SPECIFICATIONS BY TRANSLATION TO PROLOG

Öz

Formal methods of software development rely on the validation of the specification of the software. Such specification is normally expressed in a formal language such as Z. However, in order to be validated the Z specification must be tested, and to achieve this it has to be transformed into a form that can be executed or animated. Prolog was one of the languages used for animation of Z specifications. This paper explains the techniques used for translating Z schemas into Prolog predicates. It also examines some of this translation shortcomings and unreliable features.
