Source Integration is one of the core problems in Data Warehousing. Two critical factors for the design and maintenance of applications requiring Source Integration, and in particular Data Warehouse applications, are conceptual modeling of the domain, and reasoning support over the conceptual representation. We present a novel approach to conceptual modeling for Source Integration, which allows...

Since the late 1980s, there has been a growing interest in the use of foundational ontologies to provide a sound theoretical basis for the discipline of conceptual modeling. This has led to the development of ontology-based conceptual modeling techniques whose modeling primitives reflect the conceptual categories defined in a foundational ontology. The ontology-based conceptual modeling languag...

A core activity in information systems development involves understanding the conceptual model of the domain that the information system supports. Any conceptual model is ultimately created using a conceptual-modeling (CM) grammar. Accordingly, just as high quality conceptual models facilitate high quality systems development, high quality CM grammars facilitate high quality conceptual modeling...

Web conceptual modeling is a young discipline, which is gaining popularity among Web developers and CASE tool vendors. However, most conceptual models for the Web proposed so far are an evolution of hypermedia models, and pay attention mostly to the specification of data structures and navigation primitives. As the Web becomes a vehicle for implementing B2B applications, the need arises of exte...

Empirical research is an important methodology for the study of conceptual modeling practices. The recently published article “Representing Part–Whole Relations in Conceptual Modeling: An Empirical Evaluation” (Shanks et al. 2008) uses the lens of ontology to study a relatively sophisticated aspect of conceptual modeling practice, the representation of aggregation and composition. It contends t...

Conceptual Modeling-based methods and their corresponding CASE tools have traditionally had one main weak point: the use of different notations for the problem space system view (centered on the what the system is) and the solution space view (centered on the how it is to be represented). The real value of Conceptual Modeling, from a pragmatic perspective, is lost due to these different notatio...

Abstract: The implementation of government legislation, social responsibility, environmental concerns regarding the reduction of waste, hazardous material and other consumer residuals have made the competition between the firms stricter than ever and nowadays firms that want to survive need a more productive and innovative approach toward the financial aspects of their businesses.his pape...
