NTT Docomo, Inc. has been providing mobile communication services, primarily for mobile phones, under the slogan of "Creating new communications culture" as Japan's largest mobile communications carrier. In 2015, NTT DoCoMo revamped their "Traffic data warehouse" that handles traffic data for the billing/settlement system using Microsoft SQL Server 2014. As a result, quick analysis and usage of billing data was enabled for more than 66 million subscriber lines to further improve customer service. Software maintenance costs have been significantly reduced (by about 75%) compared to the previous ratio. As a result of integrating a combination of the old DWH (Data WareHouse) database and analysis tools to SQL server 2014, additional expenses for analysis tools, etc. are no longer incurred.
