Enterprise data warehouses are often very large systems and serve many user communities. Data warehouse play a key role in the business intelligence and crucial decision making. In addition to the normal data warehouse functionalities, they require flexible and powerful security features. It is expected that the security capabilities must seamlessly be incorporated in an environment which has stringent performance and scalability requirements.This paper advocates new concept of security design i.e. depicting security mechanisms at conceptual design stage itself using multidimensional modeling. VPD has been selected as the tool to be used in the implementation phase that satisfies the security mechanism depicted at the design stage.Keywords

Analysis is a process of understanding data more precisely. The process of analysis differs according to the data we are trying to analyze. Typical steel product manufacturing involves many processes running 247 in sequence comprising of different process units. These process units have sensors generating useful data for process control. These parameters have to be analyzed and monitored in real time to get a good quality product.
The conventional methods to analyze these data are inefficient. Hence, in this paper we present an approach for analysis that combines various process control and quality control parameters, uses online analytical processing (OLAP) system and provides flexibility to the user for necessary analysis.
