A fully automatic translation of unified modeling language (UML) models to complete source code is not reported so far because some implementation details will not be there in the model, or a single UML model is not enough for complete code generation, or some model elements may not be directly convertible to source code. These issues are addressed in this study. The authors take workflow modelling and automation as the focus of their research. Hence, UML activity diagram is considered. Activity diagram alone cannot give the implementation details like object interactions. A formal association is found between activity and sequence diagrams to add object interaction details to the work flow. Moreover, the authors formulate an algorithm, Am_To_Prototype, which is composed of two subroutines named Method_Body & Excecution_Logic, to generate code from the combined model of activity and sequence diagrams consisting of concurrent activities. The authors compare the proposed method with other research outcomes with respect to workflow automation, support for concurrency, etc. The proposed algorithms are able to generate class definition, method definition and control flow. A case study is presented that demonstrates the algorithm, to generate Java code for the ATM operation. [ABSTRACT FROM AUTHOR]

Unified modelling language (UML) is a visual modelling language, which has gained popularity among software practitioners. In a model‐driven software development environment, the existing UML tools mainly support automatic generation of structural code from UML class diagrams. However, the code generation from UML diagrams such as statechart, activity, collaboration and sequence diagrams (SDs) are not supported by most UML tools and also have scarcely been reported in the literatures. This work proposes an approach to automatic generation of code from UML 2.x SDs of use cases. From the XML metadata interchange (XMI) representation of an SD of a use case, the authors construct a graph model called sequence integration graph (SIG). The SIG encapsulates information related to messages, control flow and method scope of interactions. These information are then used to generate code. The proposed approach has been tested using a number of real‐life application systems and the results substantiate the efficacy of the approach to synthesise the code for controller classes. The authors observe that approximately 48% of the total lines of code within controller class methods can be generated with the proposed approach. The proposed approach can be easily extended to other behavioural UML models such as interaction‐overview diagrams, communication diagrams and activity diagrams. [ABSTRACT FROM AUTHOR]
