SQuaRE-Aligned Data Quality Model for Web Portals

The Internet is a perfect environment for the daily exchange and publication of data, and Web portals serve as an important means to access information worldwide. Those who use these applications may find a considerable amount of data which might equally be correct or incorrect. However, it is important to attain useful data and suitable information since consumers use it in their everyday tasks. We therefore identify the need to evaluate data quality in Web portals and define a data quality model, denominated as SPDQM (SQuaRE Portal Data Quality Model), which is based on a previous model, PDQM (Portal Data Quality Model) and the ISO/IEC 25012, the Data Quality standard, part of the SQuaRE (Software product Quality Requirements and Evaluation) family.
