Integrador de Sistemas Heredados: una soluci?n para la Integraci?n de Informaci?n

Abstract

The Legacy information systems were created with the purpose of automate process that before of the informatics invention were made in a manual way, these systems have gained prominence over the years because organizations have become increasingly dependent of them, and the information they generate and manage have a great value. Nowadays new tendencies and paradigms make that business and organizations base the majority of their process in information systems and it is imperative that new technology can works together with legacy systems, for this reason the information must be integrated. Therefore under this context, is necessary to raise an alternative solution for integrating information of different legacy systems. In this thesis, is examined the problem, is described the importance of legacy systems in contrast with new current technological tendencies, besides is analyzed tools which we can achieve information integration and is purposed an alternative solution to problem through a multiplatform information system integrator, additionally, it proposes a integration methodology, leaving an established base to perform the development of a new system in order to replace the legacy system. The proposed solution has been proven through a case study in a business tourism sector, which was able to verify: that it is possible to integrate information from a system that handles flat files, display the information on a web interface for example, and start migration to a new relational database. After completing the proof of solution, we can say that this can integrate information regardless of the operating system and can be used in different organizations or companies.

Hoy en d?a con las nuevas tendencias y paradigmas hacen que los negocios y organizaciones basen la mayor?a de sus procesos en los sistemas de informaci?n y es imprescindible que la nueva tecnolog?a conviva con los sistemas legacy o heredados; por tal motivo la informaci?n debe ser integrada. Bajo este contexto, es necesario plantear una alternativa de soluci?n que permita integrar la informaci?n de diversos sistemas legacy o heredados. En la presente tesis, se analiza el origen del problema, se describe la importancia de los sistemas legacy o heredados frente a las nuevas tendencias tecnol?gicas actuales, se analiza las herramientas con las que podemos lograr integraci?n de informaci?n, y se propone una alternativa de soluci?n al problema mediante un sistema integrador de informaci?n multiplataforma adaptable a cualquier tipo de negocio. Adicionalmente, se propone una metodolog?a de integraci?n que deja una base establecida para realizar el desarrollo de un nuevo sistema que reemplace al sistema legacy o heredado. La soluci?n propuesta ha sido probada mediante un caso de estudio en una empresa del sector turismo, donde se pudo verificar: que es posible integrar la informaci?n de un sistema que maneja archivos planos, mostrar la informaci?n en una interfase Web por ejemplo, y empezar la migraci?n hacia una nueva base de datos relacional. Despu?s de realizadas las pruebas de la soluci?n se puede afirmar que esta puede integrar informaci?n sin importar el sistema operativo y que puede ser usado en distintas organizaciones o empresas.
