Abstract: In this research review paper, we have introduced our work with a comprehensive study on data warehousing, regarding to its novelty; depending on that, there was an intensive research work, because of its importance and need nowadays, we have reviewed and studied big amount of researches available in the Information Systems research centers around the globe. We have focused on optimization in our comprehensive studies and also on the processes of data warehousing with respect to its updated optimized queries approaches and its vast utilization in the Market. We found that ,the most useful information extracted by using both approaches which have used within new optimized techniques for query-driven approaches, has got potentially effected on the strategies of most successful data warehousing integration models. arabic 9 English 68

Abstract:- Our research paper has presented a new developed model for secured search into a big data of document collections. The developed model has investigated the importance of secured search and also the need for its practices in the real world. We have actually, studied both side of encryption in practical techniques issues and theoretical issues to improve the integration of information retrieval and cryptographic methods used for secured searching. We have chosen 3DES encryption technique to encrypt document data collections. Our new developed secured model has provided an efficient secured searching and/or security and authenticity over all. arabic 9 English 58
