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.

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).

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.

A conceptual model of groupware
Proceedings of the 1994 ACM conference on Computer supported cooperative work - CSCW '94, 1994This paper discusses a conceptual model of groupware consisting of three complementary components or models: a description of the objects and operations on these objects available in the system; a description of the activities (and their orderings) that the users of the system can perform; and a description of the interface of users with the system ...

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 ...

A Conceptual Model for the Web
2000Most documents available over the web conform to the HTML specification. Such documents are hierarchically structured in nature. The existing graph-based or tree-based data models for the web only provide a very low level representation of such hierarchical structure.

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.

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

Archives of General Psychiatry, 1966
REASONS why sleep occurs and is necessary are not understood. Various models are more notable by their obvious inadequacy than by their reconciliation of a wide variety of observations. Both apparent common sense and the considered judgment of authorities "hardly doubt the metabolic basis of the nervous exhaustion . . .

A Conceptual Model of the Blockchain
2020Hyperledger Fabric is a very large project under the umbrella of the Linux Foundation, with hundreds of developers involved. In this paper we will illustrate how the application of fact-based modeling will help us in understanding some basic features of the blockchain concept as is used in Hyperledger Fabric (HLF) and that it can serve as a conceptual ...
