Di Z notation na one formal specification language wey dem dey use to describe and model computing systems. E dey target di clear specification of computer programs and computer-based systems generally.

For 1974, Jean-Raymond Abrial publish "Data Semantics". E use one notation wey later dem go dey teach for University of Grenoble until di end of di 1980s. While e dey for EDF (Électricité de France), Abrial write internal notes on Z. Di Z notation dey use for di 1980 book "Méthodes de programmation".

Z originally propose by Abrial for 1977 with di help of Steve Schuman and Bertrand Meyer. E develop am well well for di Programming Research Group for Oxford University, where Abrial work for early 1980s, after e don reach Oxford for September 1979.

Abrial talk say Z get di name "Because it is the ultimate language!" even though di name "Zermelo" dey associated with di Z notation through di use of Zermelo–Fraenkel set theory.

Z dey based on di standard mathematical notation wey dem dey use for axiomatic set theory, lambda calculus, and first-order predicate logic. All expressions for Z notation dey typed, so e dey avoid some of di paradoxes of naive set theory. Z get one standardized catalogue (wey dem dey call di "mathematical toolkit") of commonly used mathematical functions and predicates, wey dem define using Z itself.

1. Wetin be di computer system wey di article dey talk about?
2. Wetin e dey target?
3. Who create am?
4. Wetin e publish for 1974?
5. Where dem dey teach di notation?
6. Which book dey use dis notation?
7. When dem publish di book?
8. Who help am create am?
9. Who else?
10. Where dem develop am?
11. Why e get di name wey e get?
