Conceptual Modeling in the eXtreme

Information and Software Technology, 2002
Abstract 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).

Workflow management is emerging as a challenging area for databases, stressing database technology beyond its current capabilities. Workflow management systems need to be more integrated with data management technology, in particular as it concerns the access to external databases.

Conceptual modelling for simulation Part II: a framework for conceptual modelling

Journal of the Operational Research Society, 2008
Summary: Following on from the definition of a conceptual model and its requirements laid out in a previous paper, a framework for conceptual modelling is described. The framework consists of five iterative activities: understanding the problem situation, determining the modelling and general project objectives, identifying the model outputs, identify ...

Levels for Conceptual Modeling [PDF]

open access: possible, 2011
Usually object types are organized in taxonomies by means of a specialization relation (also called subtyping or isa) 'implemented' by means of inheritance. This paper proposes a (non-incompatible) alternative to taxonomies that relies on three primitives: grounding, a specific kind of factual existential dependence, extensional atemporal parthood, and

A Conceptual Model for Tables

1998
We describe a new, simple conceptual model for tables. The conceptual model treats a table as a map that has a domain which is a product of categories or index sets and a codomain which is a set of entry values. We demonstrate how we can use the model to specify the semantics of some tabular editing operations.
