Implementation of a Platform for Data Quality Analisys

There are many accessible sources relations. Users need to access in a uniform way to these sources, even they are heterogeneous and independents. Give users uniform answers with high quality data becomes difficult.

Queries can have different results depending on the calculation process used to solve them. It becomes necessary to study results data quality in order to give users the one that is better adapted to their needs.

This document presents the design and implementation of a platform that allow user to evaluate calculation process quality. Data quality properties can be calculated used algorithms that execute over the platform. New algorithm designed for calculate new data quality properties can be plugged in the platform in an easy way.
