This paper describes an approach to On Line Analytical Processing (OLAP), expresed in the declarative programming paradigm.
We define a collection of functions that capture some of the functionality currently provided by multidimensional database product. This is done by defining…

La obtención de conocimiento a partir de la información existente es un proceso no trivial que consiste en identificar patrones válidos, novedosos, potencialmente útiles y comprensibles a partir de los datos disponibles. La Minería de Datos es el área de…

A Federated System is a collection of independent, cooperative, possibly heterogeneous and autonomous computer systems (usually database systems) which allows sharing all or some of its data. A Service-oriented Architecture is an application architecture whose functionalities are defined as independent…

The software architecture role in agile methodologies is not sufficiently documented or formalized by means of a process consistent with the philosophy. The current work’s contributions are: 1) Defining guidelines to implement architecture practices in an agile way and so…

Although researchers noted the importance of effective communication among stakeholders, it continues to be a challenge for requirements engineering. Communication can be considered as a management tool since communication allows organisation’s personnel to produce a cohesive enterprise view. In this…
