Transaction systems are at the heart of modern commercial and financial activities, covering a wide range of scenarios from e-commerce order processing to real-time clearing for financial institutions. Such systems typically require high concurrency processing capabilities, real-time data storage and efficient retrieval functions, as well as a balance between data consistency and performance. As the size and complexity of transaction data continues to grow, traditional transaction system architectures are often limited by fixed table structures and lack of horizontal scalability in addressing these challenges.
MongoDB, as a distributed document-based database, with its flexible architecture, high throughput capability and built-in transaction support, provides a modern solution for building complex and efficient transaction systems that can meet diverse business needs.
