We are confident that our results would be extremely useful for the Automation of Modular Transformations in the future. These were also adequately justified by the students during their viva. More than 90% of the students also agreed with the possibility of transforming Associative Entities into Entity Classes. More than 90% of the students gave positive responses in both the surveys, with regards to the feasibility of transforming ERDs to Class Diagrams. To test the validity of this new discovery, a second experiment was conducted with a different batch of students, this time in two stages, the first stage being a replication the first experiment and the second stage being a viva where the students had to justify their responses to the survey. A surprising discovery of this experiment was that there was a third possible method of Transformation from ERDs to Class Diagrams, which included the Transformation of Associative Entities (of ERDs) into Entity Classes (of Class Diagrams). Online use case diagram drawing tool free software#An experiment was conducted to determine which of the two Transformation methods suggested in two previous International Research publications were more feasible and it was a survey where the respondents were a batch of computer science students, of the Colombo University, Sri Lanka, whom we considered to be future experts in the domain of Software Engineering. And so, the similarity can be utilized to generate requirements specification from DFD to UML Diagram.Īccording to the literature surveyed, this is the first ever publication which contains the complete details of an experimental validation the Transformation from Entity Relationship Diagrams (ERDs), to Class Diagrams. Furthermore, the factors involved in the similarities are found. Then, the method is tested with the case study of DFD and UML diagrams. Established along the similarity methods, this paper will define the syntax rules of DFD Level 0, DFD Level 1, UML Use Case Diagram and Sequence Diagram. This paper proposes a framework which is acquired from the syntax rules for DFD and UML. It is also serves as a documentation for the upcoming development of new systems. In the end, they produced a new UML diagram as a design material and the implementation of new systems. Most researches are concentrated on converting the existing DFD to UML diagram. Nowadays, there is an intensive research for model transformation, integrating and merging from structured to object-oriented approach. In SDLC, DFD (data flow diagram) specification is used, meanwhile UML (unified modelling language) specification is used for the object-oriented approach. During analysis and design, requirements specification can be documented using two (2) mostly methodologies which are SDLC (software development life cycle) and OOSAD (object-oriented system analysis and design). This situation needed software engineering to produce dependable and trustworthy systems economically and rapidly. Today, individual and society relies on innovative software systems.
