前一版的重複序列資料庫是建立在集中式資料庫系統上的，此資料庫目前包含了大量的資料，而生物資訊的資料也日漸擴增，重複序列資料庫的效能成為很重要的問題。為了得到更好的效能，我們建立了分散式重複序列資料庫。在分散式資料庫上，資料分散的方法是平衡負載的重要機制。我們設計了許多資料分散的方法來做實驗以得到最適合重複序列資料的方法，也發展了智慧型元件來輔助我們的系統以得到更好的效能。 The original version of Repeat Sequence Database (RSDB) was created based on centralized database systems (CDBSs). It contains large number of data currently, and the size of biological data is increasing rapidly. The performance of RSDB becomes an important issue. Distributed RSDB (DRSDB) is created based on distributed database systems (DDBSs) in order to obtain better performance. Data distribution serves as an important load-balancing mechanism. We design lots of data distribution approaches and try to find the proper approaches to our particular system with experiments. The results show that query processor does not always choose the right data access paths for queries, and we develop an intelligent component to assist our system executing queries wisely in order to obtain much better performance.
