Journal of Intelligent Computing Michal Kvet, Karol Matiaško 8 4 2017 http://www.dline.info/jic/fulltext/v8n4/jicv8n4_2.pdf Database systems and temporal extension is core part of the data and information system processing. However, temporal paradigm has never been standardized. Object level temporal approach is based on extension of the primary key, whereas our approach uses column granularity, thanks to that, sensorial data with various granularity and frequency of changes can be effectively managed and accessed. Moreover, significant performance parameter is just index structure and mostly used B+tree. Such developed index cannot manage and deal with NULL values, therefore in this paper, we propose effective solution for storing undefined attribute values as well as time attributes delimiting validity.
