We present Oz as a programming language that naturally encompasses multiple styles of programming, including (constraint) logic, functional, and concurrent object-oriented programming. This has been achieved by providing a common underlying foundation for these styles by means of a simple formal model in the concurrent constraint paradigm. An integrative programming model is argued to be useful for foundational as well as practical reasons, and is illustrated by means of paradigmatical code examples.
