oml

OML is an acronym with multiple meanings across different domains. In mathematics education, two U.S. competition programs use the abbreviation: the Online Math League and the Oregon Math League. In software engineering, Object Modeling Language has been used to denote a modeling notation in some projects.

Online Math League (OML) is a web-based contest program for K–12 students. It provides periodic problem sets, online submission, and scoring, and is used by schools to provide regular practice and assessment in mathematics.

Oregon Math League (OML) is a state-level mathematics contest administered by the Oregon Council of Teachers of Mathematics. It organizes team and individual rounds that emphasize problem solving and mathematical reasoning.

Object Modeling Language (OML) refers to a modeling approach used in certain software development efforts to describe objects and their interactions. It is not as widely standardized as UML, and its usage varies by project or organization.

Because the acronym OML is used in different fields, the intended meaning is usually clear from context. This article highlights a few common uses, while other meanings may exist in additional domains.
