Multimedia data modelling is radically different from the traditional data modelling due to the special requirements imposed by multimedia data. One fundamental issue of concern is the notorious "semantic gap" between what were stored in the database, ...

This paper considers conceptual modelling for three purposes namely data modelling, knowledge modelling and ontology modelling. It differentiates between the nature of the conceptual models for these three. It then proposes a representation suitable for ...

Modeling is core software engineering practice. Conceptual models are constructed to establish an abstract understanding of the domain among stakeholders. These are then refined into computational models that aim to realize a conceptual specification. ...

This paper introduces a Conceptual Data Model for Data Warehouse including multidimensional aggregation. It is based on Entity-Relationships data model. The conceptual data model gracefully extends standard Entity-Relationship data model with ...

There is an increasing community of researchers trying to draw attention to the importance of evaluation issues. Some approaches can be followed to evaluate the quality of software, but gives no guidance on how to construct a high quality software ...

Model-driven development is the process of creating models of a software system and transforming them into source code. Since the stepwise transformations can be done automatically or by hand, the notations of the models should be both precise and ...

We identify established tableaux techniques as an invaluable tool for semantic knowledge acquisition in the design process of relational databases.

Sample databases allow users and designers to judge, justify, convey and test their understanding of the ...

On a high level of abstraction a Web Information System (WIS) can be described by a storyboard, which in an abstract way specifies who will be using the system, in which way and for which goals. While syntax and semantics of storyboarding has been well ...

In business processes, knowledge-intensive tasks are ones in which the people performing such tasks are involved in a fair degree of uncertainty. These people are required to apply and bring together their experience, training, expertise and judgement. ...

The work presented in this paper targets the software integration on the level of business process models. The goal is to create the behavioural description of an integrated system that is consistent with the behavioural descriptions of the original ...

Business process modeling entails the capture of a set of tasks that invariably model the functional behavior of a system. Another aspect of business process modeling involves the accurate capture of operational behavior and the associated process ...

Over the last few years, the web is establishing increased importance in society with the rise of social networking sites and the semantic web, facilitated and driven by the popularity of client-side scripting commonly known as AJAX. These allow ...
