A data warehouse is a federated repository that collects and stores large amounts of data under a single location and architecture, providing a unified access point for users across the organization. It's particularly important in customer relationship management (CRM) applications, where it can help improve business intelligence, data standardization, and decision-making by making CRM data safe and accessible to other groups within the enterprise. While CRMs are great tools for managing customer data, they have limitations, such as not being able to build or manage a website, Enterprise Resource Planning (ERP), or in-depth project management. Moving CRM data to a data warehouse can help overcome these limitations by providing a centralized location for all company data, enabling improved business intelligence, and automating data analysis and reporting. The benefits of moving CRM data to a data warehouse include improved customer insights, enhanced decision-making, consistent data interpretation, data standardization, and a "bird's eye view" of the entire enterprise. To plan and prepare for this migration, companies need to identify the data they want to move, choose their data warehouse solution, develop a data migration plan, and perform necessary steps such as preparing the team, reviewing source and target CRMs, performing data mapping, securing a complete data backup, running a test migration, and implementing post-migration validation activities.
