“…We recall that the data model and its visual representation are two distinct aspects of the interface and different mappings can be established among them (see (Batini et a!. 1993) and (Haber Joannidis Livny 1994)), but it is surely a good choice to try to improve both of them.…”

The significance of usability as one of the most important system characteristics is widely recognized in all the application fields, including databases. This also implies the involvement of the user in the activities of design and testing of any interface. However, very few studies aiming at validating the usability of a system have been proposed in the database field, in contrast to many other computer science areas. In this paper we present an experiment comparing, from the point of view of the ease-of-use, a novel visual query language, namely QBD*, against a well-known traditional textual language such as SQL. The results of the experiment confirmed the superiority of the QBD* approach, which is based on a conceptual data model, closer to the user view of the reality than the relational model, a visual representation of such a model, more attractive and graspable than a textual list of table names, and direct manipulation commands, having a syntax much more easier than the SQL one.

The literature on product-based workflow design considers only static collaborative environments where the product model is static and does not change. However the possible evolution of the product model and thus its impact on the collaborative environment are not considered despite the importance of this evolution for innovative product design. As a result the uncontrolled changes can easily break the crossorganizational process that links the different stakeholders in the collaborative environment. In this paper we present a framework that builds the collaboration contract from the product model and supports a controlled evolution of this contract. We leverage this framework by a set of management operations (services) that enable the contract evolution and investigate how a tailoring operation will not impact the executable cross-organizational process unless this process is maintained executable by the workflow engine. These operations are provided as services by a collaborative platform and displayed through a standard-based user interface.

“…Some insights on metaphorical design are given in (Marcus, 1994;Madsen, 1994). In database interfaces, metaphors have been exploited for representing the intensional part of the database, that is the data schema; in such cases, the metaphor mediates between the data model and the user (Haber et al, 1994;Catarci et al, 1995). Most end users are actually concerned with the extensional part of the database, therefore it is appropriate to offer them a scenario where the information contained in the database is metaphorically represented in a VR environment, i.e.…”

In this paper we discuss how metaphors for supporting user interaction with multimedia databases can be automatically generated. The work presented is a further step in the development of Virgilio, a Virtual Reality (VR) based system that has been designed to be a general purpose exploration tool for highly structured data. Virgilio visualizes the results of a query to a database by generating VR scenes, that exploit appropriate metaphors in order to take advantage of common knowledge about real world objects, thus reducing the cognitive load in the process of information assimilation. We analyze two specific components of the Virgilio architecture, the Query Management Tool and the Metaphor Definition Tool, and we identify a completely automatic procedure to define the metaphor that will be exploited in the construction of the VR scene. The implementation of this procedure exploits the backtracking search strategy of Prolog interpreters to solve a typical constraint satisfaction problem.
