Building an EDW and BI Solution in the Cloud Using Highly-optimized Data Architectural and Analytics Approach

Overview & Challenge

Our client, a telecommunication service provider in the United States, wanted to establish an efficient mechanism for BI and Analytics. The main business driver was to embrace the opportunities presented by data warehouse as a unified and super-fast storage system, minimizing inconsistent reports and providing the capability for data sharing, resulting in significant returns through revenue growth, increased fact-based decisions, and innovative customer engagement campaigns.
