In this research paper entitled "Development of a system based on Oriented Architecture Models for Transformation of a Class Diagram to Source Code Java Computational Model", we propose an algorithm for improving the processing of class diagrams to source code as for the time and complexity, based on models oriented architecture._x000D_ For this research 8 different models Transformation Class Diagrams to Java Source Code were analyzed; which analyzes one to one obtaining the advantages and disadvantages. With them we start with the development of the model we eventually propose._x000D_ The proposed computational model consists of 3 phases: Modeling, Trial and Transformation. In the first phase the Class Diagram is used to formalize the necessary data are then used in the next phase of Instance. In this second phase, the metamodel class is used so that, from this, to create an instance; ...
