Design, Implementation, and Assessment of Innovative Data Warehousing; Extract, Transformation, and Load(ETL); and Online Analytical Processing(OLAP) on BI


Ramesh Venkatakrishnan, Colorado Technical University, USA


Abstract


The effectiveness of a Business Intelligence System is hugely dependent on these three fundamental components, 1) Data Acquisition (ETL), 2) Data Storage (Data Warehouse), and 3) Data Analytics (OLAP). The predominant challenges with these fundamental components are Data Volume, Data Variety, Data Integration, Complex Analytics, Constant Business changes, Lack of skill sets, Compliance, Security, Data Quality, and Computing requirements. There is no comprehensive documentation that talks about guidelines for ETL, Data Warehouse and OLAP to include the recent trends such as Data Latency (to provide real-time data), BI flexibility (to accommodate changes with the explosion of data) and SelfService BI. This research paper attempts to fill this gap by analyzing existing scholarly articles in the last three to five years to compile guidelines for effective design, implementation, and assessment of DW, ETL, and OLAP in BI.


Keywords


Business Intelligence, ETL, DW, OLAP, design implementation and assessment

HYBRID ENCRYPTION ALGORITHMS FOR MEDICAL DATA STORAGE SECURITY IN CLOUD DATABASE

Image
  HYBRID ENCRYPTION ALGORITHMS FOR MEDICAL DATA STORAGE SECURITY IN CLOUD DATABASE Fenghua Zhang1，Yaming Chen2，Weiming Meng3 and Qingtao Wu4 1Computer Technology, Henan University of Science and Technology, Luo Yang, China 2,3Computer Science and Technology, Henan University of Science and Technology, Luo Yang, China 4Professor, Henan University of Science and Technology, Luo Yang, China ABSTRACT Cloud database are derivatives of Cloud computing. At present, most medical institutions store data in cloud database. Although the cloud database improves the efficiency of use, it also poses a huge impact and challenge to the secure storage of data. The article proposes a hybrid algorithm to solve the data security problem in the hospital cloud database. First, the AES algorithm is improved. The improved algorithm is called P-AES algorithm. The P-AES algorithm is then combined with the RSA algorithm, called a hybrid algorithm. The experimental results show that the hybrid enc...
