Title: A Database
Querying Tool for Naïve Users
Abstract: In order
to formulate valid queries on a relational database, one must be fluent in
SQL (Structured Query Language), the concepts that it involves (entities,
relations, attributes) and the stored data schema describing the elements
of the domain. However, casual users are not familiar with query languages
and database structures, but would like to access data in a more user friendly
way. The goal of this paper is to present a tool that allows casual
users to easily build a query using an almost natural language, on a step
by step basis, guided by the tool. The tool here described was actually implemented
based on two pre-requirements: all relationships of the ER (Entity-Relationship)
Model must be description as roles and the same level of semantic information
available in the conceptual model must be available in the physical model.
