The paper presents an algorithm for automatic layout of class diagrams. The presented algorithm efficiently and openly tries to lay out a diagram in the landscape format using a modified Sugiyama algorithm. The proposed algorithm is implemented as an Eclipse plug-in and works within Papyrus class diagram modeling projects.

The paper presents an approach to web-based visualization of automatically generated data models, which combines visualization principles used in desktop applications, and usage of web-based technologies. The proposed approach is implemented and integrated with an existing online system for automatic synthesis of conceptual database models based on business process models. The approach and implemented online system named AMADEOS are illustrated by an example of visualization of the UML class diagram representing the conceptual database model automatically generated based on the source BPMN model.

Existing approaches to business process model-driven synthesis of data models are characterized by a direct synthesis of a target model based on source models represented by concrete notations, where the synthesis is supported by monolithic (semi)automatic transformation programs. This article presents an approach to automated two-phase business process model-driven synthesis of conceptual database models. It is based on the introduction of a domain specific language (DSL) as an intermediate layer between different source notations and the target notation, which splits the synthesis into two phases: (i) automatic extraction of specific concepts from the source model and their DSL-based representation, and (ii) automated generation of the target model based on the DSL-based representation of the extracted concepts. The proposed approach enables development of modular transformation tools for automatic synthesis of the target model based on business process models represented by different concrete notations. In this article we present an online generator, which implements the proposed approach. The generator is implemented as a web-based, service-oriented tool, which enables automatic generation of the initial conceptual database model represented by the UML class diagram, based on business models represented by two concrete notations.

The paper presents an online two-phase business process model-driven generator of the conceptual database model. The generator is implemented as a web-based, platform-independent tool, in contrast to the existing tools that are dependent on some specific technological platform used for their implementation. Unlike the existing approaches, which are characterised by the direct synthesis of the target model based on business process models represented by a sole concrete notation such as BPMN, the presented generator uses an indirect two-phase approach, which is based on the introduction of a simple domain specific language as an intermediate layer between source and target notations. The implemented online generator enables automatic generation of the target data model represented by UML class diagram, based on business process models represented by two concrete notations: BPMN and UML activity diagram.
