PURPOSE: A device and a method for describing a metric description language, architecture of metric description language are provided to facilitate a metric technique by searching a path between meta model targets and creating a searching expression formula through an MDL(Metric Description Language) based on OCL(Object Constraint Language). CONSTITUTION: A metric input unit(100) inputs a metric, and the metric is expressed in an MDL(Metric Description Language). An MO MDL to OCL(Object Constraint Language) translator(200) creates an MDL tree structure through the analysis of the inputted metric. The MO conversion unit converts the MDL tree structure into OCL expression. An UML(Unified Modeling Language) input unit(300) inputs an UML diagram, and a calculation unit(400) calculates the OCL expression in an entity unit of an UML diagram. |
