The article discusses how using a single database design for a big information system can cause issues as more information is stored. To solve this, the authors suggest using different database types for various purposes in a hospital information system. By creating front desk, background, historical, statistical, basic, and backup databases, they aim to make the system run more efficiently. They also propose a data scheduling mechanism to transfer data between these databases, ensuring smooth system operation. The main idea is that using a diverse database setup can improve the system's performance and maintenance, leading to a stable and functional hospital information system.
