In the digital age, businesses rely on databases to store and manage critical data, including sensitive information such as customer data and financial data. However, with the explosion of data volumes, database security and compliance have become a core issue that enterprises cannot ignore. Traditional audit systems cannot accurately identify front-end users or track data changes, making it difficult to meet the requirements of laws and regulations such as the Personal Information Protection Law. The next-generation database activity monitoring system DAM+, which is innovatively developed by the company, adopts a microservice architecture and distributed cluster deployment, supports NonStop Active-Active mode, achieves high availability, uninterrupted monitoring, and has excellent flexibility and scalability. Its Smart Agent technology can accurately identify front-end users, comprehensively track data before and after data changes, and meet the 5W requirements of the Personal Information Law "who, what, when, where, and why(action)", helping enterprises achieve compliance and information security.
