Over the past decade, NoSQL database technology has seen significant growth as large enterprises increasingly adopt it for mission-critical applications, replacing traditional relational databases due to its cost-effectiveness and capability to handle modern data needs. This shift is driven by the need to overcome limitations in scalability, data flexibility, and performance associated with relational databases, leading to NoSQL's use in diverse applications such as personalization, user profile management, real-time analytics, content management, and mobile applications. Notable examples include Domino's personalized marketing, Nexon's dynamic user profiles, Wibmo's real-time transaction monitoring, and Viber's large-scale digital communication. Additionally, NoSQL supports complex tasks like fraud detection, with FICO using it for high-volume transaction analysis. Enterprises are leveraging NoSQL to enhance business agility, reduce costs, and modernize database infrastructure, often through Database as a Service (DBaaS), to meet the demands of individual business units and operate at a global scale.
