Case Study: DCM Holdings Co., Ltd. achieves 50% faster sales analysis and 40% IT cost reduction with Oracle

DCM Holdings Analyzes Sales Data 50% Faster, Reduces IT Operating Costs by 40%, and Supports Business Expansion with a Single-Vendor Solution

DCM Holdings, a Tokyo-based holding company for four home-center chains operating about 600 stores and annual revenue between $1–5B, needed to unify corporate and store operations to support growth and brand consolidation. Its key challenges were integrating disparate store-sales databases across subsidiaries, eliminating up-to-one-day transaction delays to enable faster sales analysis, reducing maintenance overhead, and performing seamless data migrations without disrupting store operations.

DCM implemented a single-vendor Oracle stack—Exadata, Oracle Database 12c (Multitenant), GoldenGate, SOA Suite, and WebLogic—migrating six databases into one engineered system. The move cut IT operating costs by 40%, reduced server racks from 11 to 4, doubled sales-data aggregation speed, and made ad-hoc sales analysis 50% faster; it also enabled uninterrupted migrations, centralized operations across subsidiaries, improved development efficiency, and simplified hybrid-cloud readiness.
