    Sequence diagram is a conceptual schema for representing behavior of a system. For performing such a task, it employs the object spec from a scenario and the sequence of messages exchanged among the objects. These elements describe a transaction of the system. Several approaches try the automated generation of conceptual models (like sequence diagram). Some of them use natural language as a starting point, but they are focused on other diagrams. Some others are focused on sequence diagram, but they do not obtain elements like combined fragments describing several logical constraints of the system. Other approaches use source code as a starting point, but source code can be related to an advanced phase of the software development life cycle. In this paper we define a method based on heuristic rules for obtaining automatically the elements of the sequence diagram (including combined fragments) from pre-conceptual schemas. These heuristic rules are implemented in the AToM3 tool and applied in a case study.

    Un método de ingeniería inversa de código JAVA hacia diagramas de secuencias de UML 2.0

    Software reverse engineering seems to be the process for helping software quality assurance and documentation in applications with low-quality analysis and design models. It also helps for decreasing maintenance cost and time. Currently, some CASE tools and research proposals assist analysts to develop reverse engineering process with UML diagrams as a result (especially class and sequence diagram). Some of them have reached experimental phases. Some others are focused more on class diagram and less on sequence diagram. A third group of CASE tools and proposals obtains sequence diagram, but the resulting diagram lacks some of the elements of the UML 2.0 specification. In this paper, we propose a method for automating the conversion of JAVA code into UML 2.0 sequence diagram, by means of the application of transformation rules for converting code elements to the diagram elements. We also present an example of the method application through a prototype named UNC-Inversor.
