Conceptual Modeling in the eXtreme
Information and Software Technology, 2002Abstract 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).

Conceptual modeling of workflows
1995Workflow 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.

Levels for Conceptual Modeling [PDF]
, 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

Rationale Models for Conceptual Modeling
2008In developing information systems conceptual models are used for varied purposes. Since the modeling process is characterized by interpretation and abstracting the situation at hand it is essential to enclose information about the design process the modelers went through. This aspect is often discarded.

Conceptual modelling for simulation Part II: a framework for conceptual modelling
Journal of the Operational Research Society, 2008Summary: 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 ...

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.

A Conceptual Model for Services
2015Models are a mainstay of every scientific and engineering discipline. Models are typically more accessible to study than the systems. Models are instruments that are effectively functioning within a scenario. The effectiveness is based on an associated set of methods and satisfies requirements of usage of the model.

Conceptual modelling is a widely applied practice and has led to a large body of knowledge on constructs that might be used for modelling and on methods that might be useful for modelling. It is commonly accepted that database application development is based on conceptual modelling.
