Abstract [en]

Abstract. To obtain value from the graphical representations that are used by different stakeholders during the system development process, they must be integrated. This is important for achieving a holistic understanding about system specification. Integration can be reached via modelling process. Currently, most of information system modelling methods present different modelling aspects in disparate modelling dimensions and therefore it is difficult to achieve semantic integrity of various diagrams. In this paper, we present the principles of semantically integrated conceptual modelling method for information system analysis and design. The foundation of this modelling method is based on interaction flows. This way of modelling is critical for the identification of discontinuity and inconsistency in information systems specifications. It also provides possibility to integrate business processes and business data, which is necessary for the integration of various architectural domains and to reach the holistic view of enterprise architecture. We have explained in object-oriented terms how interactive, structural and transitional aspects are merged. We also demonstrated the interpretation of various patterns, in terms of semantically integrated conceptual modelling method. It was shown that the method has sufficient expressive power to cover some special cases, which do not match the standard pattern of transaction. The inference rules of interactions help in reasoning about system decomposition. In this method, decomposition is graphically described as classification, inheritance or composition of concepts. SICM method is based on a single type of diagram, which enables reasoning about integration with the help of a special set of inference rules. The ultimate goal of this paper is to present the generic principles for computation- neutral modeling of service interactions.

Keywords: Conceptual modelling, Modelling aspects, Service interactions, Consistency, Value flows, Inference rules, Decomposition, Object transitions.

Abstract [en]

System modeling patterns are similar to workflow patterns, which were established with the purpose of delineating the requirements that arise during business process modeling on a recurring basis. Traditionally, only dynamic aspects are used for the specification of modeling patterns leaving aside the static aspects of business processes. The paper presents the conceptual modeling patterns where integrity of totally different aspects can be analyzed. The advantage of such a modeling approach is that it enables visualization and integration of different modeling dimensions of information system specifications using a single diagram. Many graphical representations do not allow such visualization and integration of static and dynamic aspects. We also represent graphically interpretation of the conversation for action schema by constructs of our semantically integrated conceptual modeling method.

Abstract [en]

Managing evolutionary changes, identification of discontinuities and separation of concerns is not an easy task in the area conceptual modeling in information system development. One of the fundamental problems is that most conventional conceptual modeling techniques deal with the collections of loosely linked meta-models, which are defined by the different types of diagrams. Typically, system development methods project interactive, behavioral and structural aspects of information systems conceptual representations into disparate views. Therefore, the semantic integrity of various architecture dimensions is difficult to achieve. In this paper we present semantically integrated conceptual modeling method. The advantage of this method is stability and flexibility of the diagrams to manage the constant changes of system requirements. This method provides possibility to visualize the interplay among structural, interactive and behavioral aspects. This is very important for the control of semantic integrity and to maintain a holistic representation, where external and internal views of service conceptualizations are visualized together. Such visualization is also important for separation of concerns which provides foundation for creation of modeling patterns. Modeling patterns are important for several reasons. First, they can be used for demonstration of the interplay of fundamental constructs that are used for system analysis and design. Secondly, modeling patterns are important for the evaluation of the expressive power of semantic modeling languages. It is demonstrated by case study examples that sequential, underlying, enclosing, overriding and overlaying interaction loops between actors provide the foundation for the composition of complex scenarios, which are spanning across organizational and technical system boundaries.

Abstract [en]

Most information systems development methodologies are based on conceptual modeling of static and dynamic views, which are represented by totally different types of diagrams. Understanding of the interplay among interactive, behavioral and structural aspects of specifications is necessary for identification of semantic integrity problems between business process and business data. Typically, semantic inconsistencies and discontinuities between collections of conceptual representations are not easy to detect and to comprehend for information system designers due to static and dynamic aspects of models being visualized in isolation. The goal of this paper is to present a modeling approach for semantic integration and evolution of static and dynamic aspects of conceptual models. Visualization of interplay among structural, interactive and behavioral aspects of computation-neutral representations helps to understand crosscutting concerns and integrity problems of information system conceptualizations. The main advantage of the presented conceptual modeling approach is stability and flexibility of diagrams in dealing with the evolutionary changes of requirements. Therefore, the developed modeling foundation is targeted to both business managers and information system designers for the purpose of computation-neutral integration and evolution of information systems specifications.

Abstract [en]

Abstract. Modelling method, which is defined by simple interaction loops between organizational and technical components can be viewed as fundamental elements for decomposition of complex business scenarios. This is important for separation of crosscutting concerns. The paper proposes a new graphical method that allows limited human mind to focus and to visualize one particular concern at a time. It also suggests design principles for the semantic integration of business and software scenarios. Separation of crosscutting concerns is performed on a basis of the standard transaction pattern. The presented modelling method can be used for introducing the evolutionary changes of requirements. This is important for managing complexity of information systems conceptualizations, especially when new changes are introduced.  It targets both business process modelling experts and information system designers. The ultimate goal of the new method is to construct and visualize business scenarios with a more comprehensible structure.

Keywords. Service interactions, value flows, separation of concerns, cancellation patterns.

Abstract [en]

Identification of discontinuities, separation of concerns and dealing with the evolutionary changes of requirements is difficult in conceptual modeling. Another restriction is that a limited human mind allows focusing on one particular requirement at a time in isolation. One fundamental problem is that all conventional conceptual modeling techniques are dealing with collections of loosely linked meta-models, which are defined by the different types of diagrams. Typically, system development methods project interactive, behavioral and structural aspects of information systems’ conceptual representations into disparate views. Therefore, the semantic integrity of various architecture dimensions is difficult to achieve. The difficulties are stemming from the paradigmatic mismatch between static and dynamic constructs. The advantage of the conceptual modeling approach presented in this paper is flexibility in dealing with the evolutionary changes of requirements. Visualization of interplay among structural, interactive and behavioral aspects helps to separate different concerns and to identify discontinuities of conceptual representations. It is demonstrated by case study examples that sequential, underlying, enclosing, overriding and overlaying interaction loops between actors provide the foundation for the composition of complex scenarios, which span across organizational and technical system boundaries. The presented semantic integration and system decomposition principles target both business process modeling experts and information system designers, because they are essential for introducing evolutionary changes and for managing complexity of information system conceptualizations.
