As We May Link: A General Metamodel for Hypermedia Systems
Many hypermedia models have been proposed, including those specifically developed to model navigational aspects of web sites. But few...
Building a Tool for Cost-Based Design of Object-Oriented Database Schemas
In the traditional waterfall approach for building a software application, the phases of requirements analysis, design, implementation, testing, and...
A Goal Oriented Approach for Modeling and Analyzing Security Trade-Offs
In designing software systems, security is typically only one design objective among many. It may compete with other objectives...
A Graph-Oriented Model and Query Language for Events
Different applications can be modeled by sets of interrelated events, such as, sequence of natural disaster events, events in...
PLR Partitions: A Conceptual Model of Maps
The traditional spatial data models model space in terms of points, lines, and regions. These models employ a disjoint...
A Conceptual Framework to Support Semantic Interoperability of Geospatial Datacubes
Today, we observe a wide use of geospatial databases that are implemented in many forms (e.g. transactional centralized systems,...
On Languages for the Specification of Integrity Constraints in Spatial Conceptual Models
This paper intends to classify, review, and compare the existing languages for the specification of spatial integrity constraints at...
Approximate Queries by Relaxing Structural Constraints in GIS
In the Geographic Information System (GIS) domain the evaluation of similarity among geographical objects plays an important role. This...
Ensuring the Semantic Correctness of Complex Regions
Ensuring the semantic and topological correctness of spatial data is an important requirement in geographical information systems and spatial...
Modeling Workflow Patterns from First Principles
We propose a small set of parameterized abstract models for workflow patterns, starting from first principles for sequential and...
