What does UML stand for?

UML stands for Unified Modeling Language. It is a standardized modeling language used in software engineering to visualize, specify, construct, and document the artifacts of a software system. UML helps developers and stakeholders understand and design complex software systems using various types of diagrams, such as class diagrams, sequence diagrams, and use case diagrams. This unified approach promotes consistency and clarity in software development processes, making it easier to communicate ideas and specifications among team members.

The other terms provided do not align with the standard definitions recognized in the field of software engineering. Universal Markup Language, User Management Language, and Uniform Metric Language do not exist as standardized languages or frameworks and are not recognized as common terminology within the software development or programming communities. Therefore, recognizing UML as Unified Modeling Language is key to understanding the tools and methodologies used in modern software design and architecture.
