Nowadays, sustainability is a key factor that should be considered in the software quality models. It is increasingly important how environmentally friendly is a software product, both in its execution and during its development process. Therefore, we have proposed, in a previous work, a quality model (25010+S) an extension of the ISO/IEC 25010 standard by considering aspects of sustainability on its characteristics and sub-characteristics. However, in order to make the model useful, it is necessary to identify measures for each sub-characteristic and characteristic. For that reason, the objective of this paper is to carry out a Systematic Literature Review to discover the state-of-the art in software sustainability measures.

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.
