Oz is a multiparadigm programming language including logic, functional (both lazy and eager), imperative, object-oriented, constraint, distributed, and concurrent programming.

Oz is a multiparadigm programming language including logic, functional (both lazy and eager), imperative, object-oriented, constraint, distributed, and concurrent programming.

The major strengths of Oz are in constraint programming and distributed programming. Due to its factored design, Oz is able to successfully implement a network-transparent distributed programming model. This model makes it easy to program open, fault-tolerant applications within the language. For constraint programming, Oz introduces the idea of "computation spaces"; these allow user-defined search and distribution strategies orthogonal to the constraint domain.

A canonical book on Oz programming is Concepts, Techniques, and Models of Computer Programming.

For more information, see the Mozart programming system, which is a multiplatform implementation of the Oz programming language.
