Temporal features of class populations and attributes in conceptual models [chapter]

Dolors Costal, Antoni Olivé, Maria-Ribera Sancho
1997 Lecture Notes in Computer Science  
In this paper, we identify six temporal features, three related to class populations and three to attributes.  ...  Constraints play an important role in conceptual modeling. In general, the specification of constraints, both static and transition, must be done in some logic-based language.  ...  the paper on "Temporal Features of Class Populations and Attributes in Conceptual Models" wich has been accepted for presentation at ER'97 Conference.  ...

Spatio-temporal Schema Integration with Validation: A Practical Approach [chapter]

A. Sotnykova, N. Cullot, C. Vangenot
2005 Lecture Notes in Computer Science  
By doing so, we take advantage of the expressive power of the common data model in the source schema description and inter-schema mapping definition.  ...  In our methodology, we validate the source schemas against the data model; the inter-schema mappings are validated against the semantics of the data model and the syntax of the correspondence language.  ...  MADS [3] is an object+relationship conceptual data model featuring structural, spatial, temporal, and multiple perceptions dimensions.  ...

A Geographic Data Model for Representing Ground Water Systems

Gil Strassberg, David R. Maidment, Norm L. Jones
2007 Ground Water  
This paper describes the data model framework, a simplified version of the complete ground water data model that includes twodimensional and three-dimensional (3D) object classes for representing aquifers  ...  The framework data model also includes tabular objects for representing temporal information such as water levels and water quality samples that are related with spatial features.  ...  Acknowledgments The authors thank Bridget Scanlon for providing comments on the manuscript and would also like to acknowledge Kyle Murray, Gary Weissmann, and two anonymous reviewers for their instructive  ...

Representing Temporal Information in UML [chapter]

Jordi Cabot, Antoni Olivé, Ernest Teniente
2003 Lecture Notes in Computer Science  
The UML is a non-temporal conceptual modeling language. Conceptual schemas in the UML assume that the information base contains the current instances of entity and relationship types.  ...  In this paper we extend the UML to define a set of temporal features of entity and relationship types, and to provide notational devices to refer to any past state of the information base.  ...  Gómez and M. R. Sancho for their many useful comments to previous drafts of this paper.  ...

Mine Evolution Dynamic Monitor Based on Dynamic Object-Oriented Model

Jiang Yang-Ming, Dong Qin-Lin
2011 Procedia Engineering  
This paper investigates the principal concepts of space-time and other relevant parameters in temporal GIS and Digital Mine.  ...  Secondly, the author studies object-oriented spatial-temporal data model based on the characteristics of mine. Thirdly, the object-oriented spatio-temporal mining data model is designed.  ...  A change in object causes either change in the objects of Spatial-Temporal Class, Attribute-Temporal Class, or both classes simultaneously. The conceptual schema for DOODM is presented in Figure1.  ...

Modelling the Real World: Conceptual Modelling in Spatiotemporal Information System Design

Agnar Renolen
2000 Transactions on GIS  
In this paper, an overview of different modelling principles and a selection of conceptual modelling languages are presented together with examples related to a selection of spatiotemporal problems.  ...  The various aspects of temporal GIS and spatiotemporal models have therefore been an active research field since the late 1980s, see Al-Taha et al (1994 ), Langran (1992 and the references therein.  ...  Thanks are also owed to the reviewers and to the Department of Surveying and Mapping at the Norwegian University of Science and Technology (NTNU).  ...

Chapter 3: Conceptual Models for Spatio-temporal Applications [chapter]

Nectaria Tryfona, Rosanne Price, Christian S. Jensen
2003 Lecture Notes in Computer Science  
In the UML approach, an extension of UML, Extended spatio-temporal UML [26] , is presented that addresses spatio-temporal modeling requirements.  ...  In order to satisfy the requirement for a clear, simple, and consistent notation, the extension introduces a small base set of modeling constructs for spatio-temporal data.  ...  The use of a non-standard, hybrid ER/OO model and the definition of new composite data structures for spatio-temporal properties, rather than exploiting existing features of the ER or OO models, increase  ...

Algebra-to-SQL Query Translation for Spatio-Temporal Databases [chapter]

Mohammed Minout, Esteban Zimányi
2004 Lecture Notes in Computer Science  
Although many spatio-temporal conceptual models has been proposed in the last years, users must express their queries on the underlying physical data structures.  ...  In particular, Christine Parent is the initiator of the MADS model and provided the original definition of the MADS algebra.  ...  We continue to study the problem of query translation, in particular the translation of spatial and temporal operators.  ...

Management of multi-scale forest resource data over time

Jussi Rasinmäki
2007 Dissertationes Forestales  
The temporal aspect of the methods consists of lifetime management for the objects and their attributes and of a temporal succession linking the objects together.  ...  The methods developed are based on a conceptual view of a forest as a hierarchically nested collection of objects that can have a dynamically changing set of attributes.  ...  To facilitate the analysis of change over time, the data model contains a class for events that drive the changes in spatio-temporal features.  ...
