Payments Modernization and the Role of the Operational Data Layer

The article discusses the need for payment modernization in light of changing customer expectations, regulatory demands, and advancing technologies. It highlights two approaches gaining prominence in payment system modernization - domain-driven design and microservices architecture. An operational data layer (ODL) is considered crucial in this process as it centralizes and organizes siloed enterprise data, making it available to consuming applications. MongoDB's flexible data model, built-in redundancy, automation, and scalability make it an ideal choice for implementing these modernization strategies.
