up::requête #s/informatique
- R(a, b, \dots)
- \varphi \wedge \psioù- \varphiet- \psisont des requêtes valides
- \exists y \varphioù- \varphiest une rête valide (et- yest une variable)
Exemple
- \text{ans}(r) \leftarrow \text{film}(t, r, a), \text{réalisateur}(r, n)en calcul conjonctif :
- \{ r \mid \exists t, a, n \text{film}(t, r, a) \wedge \text{réalisateur}(r, n)\}
