In the competitive landscape of the digital economy, retail and eCommerce companies strive to enhance customer experience and operational efficiency by leveraging NoSQL databases like Couchbase. These companies need to meet high customer expectations for personalized engagement and instant service while reducing operational costs, especially during peak shopping times like Black Friday and Cyber Monday. Tesco, a prominent global retailer, has successfully utilized Couchbase for its catalog and inventory management, enabling it to handle tens of millions of products and process 35,000 requests per second, thus ensuring high performance and availability. Couchbase's distributed NoSQL platform offers flexibility with JSON, supports SQL and text-based queries, and provides easy scalability by adding nodes as needed, which is crucial for handling large data volumes and user demands. As organizations across various industries adopt Couchbase for modern applications, they can explore its capabilities through resources like the "10 Common NoSQL Use Cases for Modern Applications" ebook and a 30-day free trial of Couchbase Capella.
