چکیده
This paper is devoted to Secure Data Warehousing architecture and its data schemas We relate a feder ated databases architecture to Data Warehouse schemas which allows us to provide better understanding to the characteristics of every schema as well as the way they should be de ned Because of the con dentiality of data used to make decisions and the federated architecture used we also pay attention to data protection

Building Secure Data Warehouse Schemas from Federated Information Systems
Introduction There are many heterogeneities among preexisting informations sources, such as DataBases (DBs), particularly semantic heterogeneities (see our chapter “Semantic Heterogeneity” in [1]). Any secure Federated Information Systems (FIS) must solve them, and deal with a): how schema levels are related to security, and b): operations on schemas to convert from level to level. We present t...

Electronic health record (EHR) system facilitates integrating patients' medical information and improves service productivity. However, user access to patient data in a privacy-preserving manner is still challenging problem. Many studies concerned with security and privacy in EHR systems. Rezaeibagha and Mu [1] have proposed a hybrid architecture for privacy-preserving accessing patient records...
متن کاملIntelligent Database Designs and Query Considerations
Database optimization is one of the major concerns and the most important factor that needs to be considered when designing a very large database system. Database optimization and evaluation are usually concentrated on the query language and the organization of data. The recent advances in technologies of data-warehousing architecture, online analytical processing (OLAP), and data mining demand...
