“…If the Business Process and their task could be organized in well-defined workflows, then their behaviors would be perceived as successful from the viewpoints of end-users-despite their high complexity, the behaviors of the systems could be kept in hand. Notwithstanding this, the Web Information Systems introduced a new factor, namely, that the interaction with users cannot be defined in detail in advance [27]. The Zachman architecture/ontology provides a description framework for grasping the static and dynamic facets of the system, along with the utilization of the system by the stakeholders.…”

“…Some research has tried to arrange the disparate aspects of Information Systems into a unified framework to keep them under the umbrella of the concept of behavior of Information Systems [27,94]. The application of enterprise architecture frameworks offers a tool-set for the conceptual integration of disparate viewpoints [11,12].…”

Hyper-graphs offer the opportunity to formulate logical statements about their components, for example, using Horn clauses. Several models of Information Systems can be represented using hyper-graphs as the workflows, i.e., the business processes. During the modeling of Information Systems, many constraints should be maintained during the development process. The models of Information Systems are complex objects, for this reason, the analysis of algorithms and graph structures that can support the consistency and integrity of models is an essential issue. A set of interdependencies between models and components of architecture can be formulated by functional dependencies and can be investigated via algorithmic methods. Information Systems can be perceived as overarching documents that includes data collections; documents to be processed; and representations of business processes, activities, and services. Whe selecting and working out an appropriate method encoding of artifacts in Information Systems, the complex structure can be represented using hyper-graphs. This representation enables the application of various model-checking, verification, and validation tools that are based on formal approaches. This paper describes the proposed representations in different situations using hyper-graphs, moreover, the formal, algorithmic-based model-checking methods that are coupled with the representations. The model-checking methods are realized by algorithms that are grounded in graph-theoretical approaches and tailored to the specificity of hyper-graphs. Finally, the possible applications in a real-life enterprise environment are outlined.

“…Utilizing the mathematical theory of hypergraphs in the background, the model of IS can be scrutinized with the assistance of algorithms to check the consistency between models and their elements, for e.g., conformance and compliance to requirements at various architecture levels and at different granularities [7]. The architectural model of IS that combines Blokdijk's approach, the axiomatic design, and the Zachman framework aims at representing the structure of overall system in the sense of particular models, components within models, the interactions among them, the patterns of architecture, of architecture building blocks [20,21,28,31].…”

The development of document handling by organizations at the level of business processes and business information systems leads to the phenomenon that the majority of documents and their contents remain in semi-structured format and definite minorities of documents are directly mapped onto structured databases. The rapidly evolving technology on the database field provides the opportunity to manage directly the semi-structured documents in line with the requirements of business processes. A continuum of possible document formats may exist in business environments. The documents can be categorized by the organization of the underlying data collections and according to the necessity and capability of data included in documents as whether wholly or partially is to be structured. The most modern database technology yields tools for handling and retrieving data making use of semi-structured and unstructured data. Our proposed approach (1) on one hand provides a theoretical framework for modeling IS to shape into some structure, (2) on the other hand yields guidance for design method to employ it for practical application with the extension of specific elementary models. The proposed modeling method that places the emphasis onto the documents and their symbiotic life with processes helps in understanding the behavior of most modern information systems. As a result, the combination of document-centric modeling and the enterprise architecture approach gives an opportunity for a unified modeling approach that keeps an eye on Conway's thesis that B Bálint Molnár
