PHONE SERVICE Reliance Communication, India's second-largest communications company, has a digital network covering over 14,000 towns and 400,000 villages. The company's subscriber base exceeded 40 million and was growing at an annual rate of 50%. The increase in demand for Reliance's services was producing explosive growth in the systems and infrastructure required to operate the business. The need to provide accurate, timely analytics to all parts of the business was becoming more acute. One area of the company that required rapid delivery of relevant analysis was Reliance's Law Enforcement Department. The company selected the approach of using a Data Warehouse Appliance. As a result of deploying the DW Appliance, the time required to turn around a request for detailed call records shrank by over 80%, from multiple days to a few hours. In addition to the company's issues with information retrieval, the inability to load data into the data warehouse quickly enough was becoming increasingly problematic. Compared to Reliance's previous database system, the DWAppliance solution reduced the average time to load a day's worth of data by over 90%, from 2 hours to under 10 minutes How are they applying Data Warehouse and Business Intelligence technologies?
