The European Conference on Object-Oriented Programming, commonly known as ECOOP, is an annual conference covering topics on object-oriented programming systems, languages and applications. Like other conferences, ECOOP offers various tracks and many simultaneous sessions, and thus has different meaning to different people.

The first ECOOP was held in Paris, France in 1986. It operates under the auspices of the Association Internationale pour les Technologies à Objets (AITO), a non-profit organization located in Germany.

ECOOP’s venue changes every year, and the categories of its program vary. Historically ECOOP has combined the presentation of academic papers with comparatively practical experience reports, panels, workshops and tutorials.

ECOOP helped object-oriented programming develop in Europe into what is now mainstream programming, and helped incubate a number of related disciplines, including design patterns

In software engineering, a design pattern is a general reusable solution to a commonly occurring problem within a given context in software design. A design pattern is not a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that...
