Modeling Secure XML Data Warehouses
Dataware houses are most ordinarily employed in strategic decision making processes. These systems integrate heterogeneous causes which are not only restricted to their interior enterprise facts & figures but also encompass facts & figures from the WWW, the last mentioned of which have become increasingly more significant in the conclusion making method in recent years. This gives motivation to use XML extensively in implementation of data warehouses. XML facilitates data and metadata interchange in between multiple heterogeneous data sources from the web and the data ware houses. Data ware houses may contain very high sensitive information, which needs to be protected. Securing the high sensitive information is the biggest challenge in the design of data ware houses. Despite of Implementation of data warehouses Technology is used. In order to get rid of security issues, we have proposed a methodological approach for the model driven development of secure XML data warehouses.
