“…These ideas were expanded later on into a model of question-answering [3,130]. Taking as the starting point an input query, the system answers the query and then, in the course of a dialogue, tries to suggest new queries related to the input query.…”

Research on database design at PUC-Rio dates back to the late seventies and covers a broad range of topics, from the early development of the relational model to recent applications of semiotic concepts to the design and specification of information systems. This paper briefly reviews some of the major contributions of the group, from the perspective of the authors. It organizes the contributions according to the data model or to the underlying disciplines that they are based on. Within each section, the presentation follows a chronological order as much as possible.

“…A large portion of the studies has been done with the logic model approach (Braga, Laender, & Ramos, 2000;De Sean & Furtado, 1998;Gaasterland, 1997;Godfrey, 1997). The logic model approach uses first-order logic predicates to represent the semantic relationship and integrity constraints among data values.…”
