Asistente para la creación de consultas en ambientes heterogéneos

Abstract

This investigation summarizes the design and the implementation of Module to construct and to solve databases queries. There does a deep analysis of requests, which helps to understand the databases model diagrammatically, as well as the Query Wizard implementation that allow information handling by users. On the other hand, information comes from a Query Manager which is capable to obtaining them from different databases. Module are also capable to showing the whole view of databases structure, in addition to their skills for built queries over one or several Databases, whenever they are in the same RDBMS. Manager also has the responsibility for query running, get the result and sending to the Wizard making the information available for the end users.
