This short paper describes the presentation model used by the Teallach model-based user-interface development environment. Teallach's presentation model provides both abstract and concrete interactors, which are first-class objects that may be freely intermixed when building a user-interface. An example is provided showing this approach in use.
Model-based user interface development environments show promise for improving the productivity of user interface developers, and possibly for improving the quality of developed interfaces. While model-based techniques have previously been applied to the area of database interfaces, they have not been speci®cally targeted at the important area of object… (More)
Model-based systems provide methods for supporting the systematic and efficient development of application interfaces. This paper examines how model-based technologies can be exploited to develop user interfaces to databases. To this end five model-based systems, namely Adept, HUMANOID, Mastermind, TADEUS and DRIVE are discussed through the use of a… (More)
Model-based user interface development environments aim to provide designers with a more systematic approach to user interface development using a particular design method. This method is realised through tools which support the construction and linkage of the supported models. This paper presents the tools which support the construction of the Teallach… (More)
A framework for user-interfaces to databases (IDSs) is proposed which draws from existing research on human computer interaction (HCI) and database systems. The framework is described in terms of a classification of the characteristic components of an IDS. These components, when progressively refined, may be mapped to a conceptual object-oriented language… (More)
We propose a conceptual approach to defining interfaces to databases which uses the features of a fully object oriented data language to specify interface objects combined with database objects. This achieves a uniform, natural way of describing databases and their interfaces. It is shown how this language can be used in the role of data definition and,… (More)
