Recent issues identified and conceptualized for simulating business scenarios in multi-version data warehouse

• Data Warehouse provides an opportunity to analyze businesses in order to precise decision- making, various tools has been build and used for such purpose. But due to static structure of DW it is unable to manage changes in external sources, also simulating various scenarios can increase the decision efficiency, for such purpose Multi-Version Data Warehouse is proposed which contains two types of versions called real and alternative. But due to diversity in simulations two types of alternative versions has been proposed. Also for querying these versions we are extending the functionality of Synthetic Warehouse Builder. This study presents the challenges we are facing and visualizing during the extensions.
