Abstract: | 在這篇論文中,我們提出一個基於Nosql 資料庫並可擴展的批價系統,這個系統提供SQL 的介面讓使用者可以直接用熟悉的SQL語言,而不用再更改以前寫好的程式。在輸入資料時,我們依據每筆資料的電話號碼來決定他們存放的位置,以達到良好的資料相依性。因此,在做資料的join 運算時,我們不僅可以減少很多跨網路傳輸的資料量,同時也減少每台機器需要計算的資料量,如此一來,可以大幅的提升系統效能。而當用戶數量增加時,我們的系統還是能維持不錯的效能。 In this thesis, we present a scalable NoSQL-based billing system that provides SQL interface. The users can run applications written in their familiar records by their telephone number to achieve data locality in our system. Therefore, we can reduce the amount of data transfer across the network, and the amount of data RegionServers have to process in the join operation. Our system is also scalable so that the query time grows very slightly when the number of clients increases. |
