Assessing the Perspective Trends on Ongoing Issuess And Challenges in Data Warehousing

With the rising demands of the customers, the emphasis on data has been shifted from storage to analysis most recently. In this regards, data warehousing has played quite a contributory roles only till the last decade. With the evolution of data volume and complexity from multiple heterogeneous data sources, the conventional data warehousing encounters some of the problems which went unnoticed. This paper has discussed mainly the unsolved challenges and ongoing issues in data warehousing technique with an aid of existing literatures, trends of technologies, and demands of customers. The outcome of the paper shows that traditional datamining approaches suffer from various issues which were not addressed in past research work. This paper will encourage addressing the benchmarking issues, less compatibility towards real-time growing data, data integration, and ineffective techniques, there is a need to carry out investigation on this issues.
