ARGO - Um ambiente adaptativo de consultas visuais e browsing a bancos de dados relacionais.

Abstract

The objective of this work is to develop a visual querying and browsing environment for a relational database. Such environment, called ARGO, follows an interface approach for visual queries, using visual representation (icons, table) and allowing direct manipulation, producing frequently queries in dinamic way. The fundamental concern in the environment is to offer an interface that suits the user's needs, allowing that a novice user as well as an expert one feel comfortable to use the system. ARGO is composed by four interfaces: Basic, Medium, Experient and Specialist. An user category can be updated as the user gets more knowledge about the system, since an interface that is more adequate to an user at one especific moment may not be adequate at another moment. ARGO adapts itself to those changes in the user behaviour or expertise, providing the more appropriate interface to the user.
