This Guidance shows how you can build a well-architected customer data platform with data from a broad range of sources, including contact centers, email, web and mobile entries, point of sale (POS) transactions, and customer relationship management (CRM) systems. It explores each stage of building the platform, starting with the extraction of batched and real-time data streams. Next, this Guidance shows how to cleanse, enrich, and process the data to create a unified customer record across all data sources. Finally, the processed data is ready for analysis and collaboration, all in a restricted, secure environment where you set the controls. The data can be used to build more personalized customer experiences and to enhance the monetization of your marketing campaigns.
