Resumen
El presente trabajo pretende realizar un estudio de completitud de algunas
características técnicas que un Sistema de Gestión de Bases de Datos debe
correcto uso en la creación de sistemas de información. La necesidad del mismo
interés nacional de crear herramientas de software –en este caso un SGBD-
basado en lo mejor existente dentro de lo conocido como software libre, relacionado esta línea, en este caso el PostgreSQL. El estudio se realizó por métodos comparativos respecto a otros SGBD muy conocidos y utilizados en el mundo. Se tuvieron en cuenta en este trabajo características tales como las facilidades creación de tablas o clases, las interrelaciones y métodos de indexado, dentro de definición de datos; así como las facilidades visuales de creación
procedimientos almacenados y funciones, y herramientas de interfaz como
informes, como parte del lenguaje de manipulación de datos de cada gestor
También se estudiaron otras características típicas de este tipo de software.
The present work seeks to carry out a completed study of some of the technical characteristics that a Databases Management System should have, for its correct use in the creation of information systems. The necessity of the same part of the national interest to create software tools -in this case a DBMS- sovereign, based on the best thing existent inside that known as free software, related with this line, in this case the PostgreSQL. The study was carried out for comparative methods with regard to other very well-known and used in the world DBMS. They were kept in mind in this such characteristic work as the facilities in the creation of tables or classes, the relationships and the indexing methods, inside the data definition language; as well as the visual facilities for creation of queries, stored procedures and functions, and interface tools like forms and reports, like part of the data manipulation language each analyzed DBMS. Other typical characteristics of this software type were also studied.
