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.

Conceptual Models and Their Foundations
2019There is no common agreement which artifact should (not) be considered to be a conceptual model although the term ‘conceptual model’ is used for more than for five decades in computer science and for more than one century in science and engineering. A team from all faculties at our university has been able to develop a notion of model that covers all ...

Conceptual Modeling in a World of Models
1999Not so long ago only the very few concerned themselves with abstraction and modeling and with making sense of abstract models of the world around us. At the previous turn of century there were only 1000 living physicist. This indicates how low was the number of people who made a living from abstract work. Most people were occupied with manual work.

Automation in Construction, 1992
Computer-a ided design in architecture is still in its infancy. Although numerous packages are sold for drafting, for computation and word processing, one can hardly say that CAAD has had a significant impact on architecture till now. On the contrary, there is a serious gap between the ongoing debate on architecture amongst the leading theoreticians on

Conceptual modeling and simulation
Proceedings 1999 IEEE International Conference on Computer Design: VLSI in Computers and Processors (Cat. No.99CB37040), 2003System-level design requires behavioral models of its complex components in order to validate the designs, synthesize implementations and generate tests. Descriptions of these components are often only available as English descriptions. Developing behavioral models from natural language descriptions has been a tedious and time consuming task.

Journal of Gerontological Nursing, 1987
We believe it is necessary to focus upon these metatheoretical issues to continue scientific debate regarding the theoretical base in gerontological nursing.

The Art of Conceptual Modelling
2012Conceptual modelling is one of the central activities in Computer Science. Conceptual models are mainly used as intermediate artifact for system construction. They are schematic descriptions of a system, a theory, or a phenomenon of an origin thus forming a model. A conceptual model is a model enhanced by concepts.

Conceptual modeling in the classroom
ACM SIGMOD Record, 1989The conceptual model is the focal point of the process of database design. All activities either converge upon or emanate from the conceptual model. All structures, through mappings either into or out of the conceptual model, must be to some extent compatible with it.

Conceptual transaction modeling
IEEE Transactions on Knowledge and Data Engineering, 1989Transaction modeling, which involves capturing the dynamic properties of an organization, is seen as a necessary component in data modeling. A specification language-transaction schema based on the ACM/PCM specification language-is implemented as the transaction modeling tool.

We claim that document engineering (the systematic development of document presentations, representations and document tools) should be firmly based on explicit, formal and abstract document models. This precept is well accepted and practiced in, for example, the database community but it is, apparently, less accepted in the XML community.
