The object constraints can be described as the expressions that are used to insert important data in object oriented models. The object management group founded a worldwide standard for object-oriented analysis and design artifacts specifically the diagrams. The specification and standard, known as the unified modeling language, comprises model diagrams and the allied and associated semantics. Unified modeling language is meant for modeling and, the object constraint language is the specification and standard for specifying expressions. These expressions add essential, crucial and critical information to object-oriented models and other object modeling work products.
