If we put them together we can generate more complete source code because, activity diagram contributes to control flow and class definitions, and sequence diagram contributes to method definitions and object interactions. First one is activity centric and the latter is object interaction oriented. Even though activity and sequence diagrams are behavioural models, they model the system from different perspective. We introduced a formal method for this association. We tried to associate activity diagram with sequence diagram to include object interactions in activity diagram. In this paper, we define a method to fine tune the activity diagrams for improved code generation. Fine tuning the activity models to include those details will help in improved code generation. The actions inside each activity and the control flow between them may not be specified in activity diagrams.

Each activity in the activity diagram can be a method (function) in the program. Method definitions are not generated because activity diagrams show a high level activity model. Moreover, those works do not present any well-defined formal method for code generation. This feature, which is not exploited so far, is very much useful in automatic code generation.įew research works have been reported on code generation from the UML activity diagrams, but those works primarily concentrate on control flow generation. This is a unique feature of activity diagram compared with other behaviour diagrams like state chart diagrams. We can specify which object is responsible for which activity. Activity diagram can show the group of activities done by different objects in the system. Unlike state chart diagrams, activity diagrams are activity centric and it shows flow of control from activity to activity. Activity diagram gives the activity model of the system which shows the workflow from activity to activity. It is the only UML diagram which models control flow (work flow). Activity diagram is one of the most important diagrams for behavioural modelling. It is best suited for event driven applications since it shows the state changes of an object in its life time.īehavioural modelling is very much important in the context of automatic code generation, since it helps us to represent the control flow in the system. Hence, the behavioural models came into picture to improve the code that produced automatically. It could produce only skeletal source codes such as, skeletal class definitions. Researches in automatic code generation started with structural modelling such as class diagrams. Automatic code generation could be possible in its real sense, only when we are able to automatically generate all these implementation specific details. When a programmer implements these designs, he/she includes so many implementation specific details such as, variable declarations, initialisations, pre-defined constant values, method definitions, class definitions, etc. These designs give us the high level design details of the system. We use UML for modelling the system structure and behaviour.

UML emerged as the de facto standard for software system modelling and design. The main challenge in this field is the perfection of the code generated. 100% complete source code generation is the ultimate aim of this field. A case study is presented that demonstrates the algorithm, to generate Java code for the ATM operation.Īutomatic code generation from unified modeling language (UML) models is an interesting research area. The proposed algorithms are able to generate class definition, method definition and control flow. The authors compare the proposed method with other research outcomes with respect to workflow automation, support for concurrency, etc. 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. A formal association is found between activity and sequence diagrams to add object interaction details to the work flow. Activity diagram alone cannot give the implementation details like object interactions. Hence, UML activity diagram is considered. The authors take workflow modelling and automation as the focus of their research. These issues are addressed in this study. IET Generation, Transmission & DistributionĪ 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.IET Electrical Systems in Transportation.IET Cyber-Physical Systems: Theory & Applications.IET Collaborative Intelligent Manufacturing.CAAI Transactions on Intelligence Technology.
