“…To maintain a holistic and systematic view of the whole IS and in order to understand its functionality, a three-level approach is important, independent of the fact what kind of IS is designed. In order to understand why and how technical system components are useful and how they fit into organizational systems, three modeling levels of IS specifications are necessary: a pragmatic level, a semantic level and a syntactic level (Gustas & Gustiené, 2008).…”

According to fundamental principles of the Privacy by Design approach, the consultation of privacy issues should be embedded into analysis and design of information systems, from the early stages of system planning to implementation. In this article, the authors extend this perspective towards Privacy and Security by Design. Exemplary focusing on mobile and pervasive emergency response, as a specific area of the emergency management domain, this article conveys how the early requirements elicitation can be supported by a semantically integrated conceptual modeling method. Presenting the results of the exemplary executed elicitation processes, it contributes a concrete set of security and privacy requirements for mobile and pervasive emergency response settings. By also taking into account conflicting security goals, this article provides a substantial grounding for the development and deployment of multilaterally secure pervasive ICT that effectively supports emergency management during and in the aftermath of critical response missions.

“…Actors are represented by subsystems that are non-overlapping in functionality. Active concepts can be related by the static dependencies such as inheritance, composition and classification (Gustas, 2010;Gustas & Gustiene, 2009;Gustas & Gustiene, 2008). The graphical notation of semantic dependencies is presented in Figure 5.…”

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.

“…A small case study will be used for illustration of the tacit structural and behavioral dependencies in the relationship Send. In terms of EM approach, the relationship Send is viewed as a communication action (Gustas & Gustiene, 2008). Action names are verbs, which bind together service requester (Person), service flow (E-mail) and service provider (E-mail System).…”

“…In this article we analyze several theoretical enhancements to achieve semantic integrity of conceptualizations. The proposed solutions are illustrated by using our enterprise modeling (EM) approach (Gustas & Gustiene, 2008). It helps us to theoretically investigate the semantic power of various diagram types.…”

Information systems can be conceptualized in a number of ways. Most methodologies propose to analyze separately process and data semantics by projecting them into totally different diagram types. This system analysis and design tradition is very strong in most modeling approaches such as structured analysis as well as object-oriented design. Structural and behavioral aspects are complementary. They cannot be analyzed in isolation. Lack of a conceptual modeling approach, which can be used for verification of semantic integrity among various types of diagrams, is the cornerstone of frustration for information system architects. Inconsistency, incompleteness and ambiguity of conceptual views create difficulties in verification and validation of technical system architectures by business experts, who determine the organizational strategies. Consequently, the traditional information system methodologies are not able to bridge a communication gap among business experts and IT-system designers. Various interpretations of semantic relations in conceptual modeling approaches make the system analysis and design process more art than science. It creates difficulties to formulate comprehensible principles of decomposition and separation of concerns. Unambiguous definition of aggregation and generalization is necessary for breaking down information system functionality into coherent non-overlapping components. This article concentrates on conceptual modeling enhancements, which help to avoid semantic integrity problems in conceptualizations on various levels of abstraction. The presented conceptual modeling approach is based on a single type of diagram, which can be used for reasoning on semantic integrity between business process and data across organizational and technical system boundaries.
