title: [Optimization of the database of the hospital information system and improvement of its performance].
abstract: Optimization of the hospital information system (HIS) and its improvement method have been discussed in this paper. Our method is to divide the whole database into two separate sub-databases, one is for daily operation, and another is for query. We keep the daily-operation-database in a fixed size by deleting the historical data within a fixed time. So the hospital information system can run quickly, having a higher efficiency and a better safety.
