3. According to Section 2.1 of Textbook, some websites are powered by databases in the back end and some are not. What are the purposes of using databases?

由於科技的蓬勃發展，帶動一連串大量資料的出現，因此如果以人力來處裡這些龐大的資料，將會耗時而徒勞無功。所以在現今 Internet 的運用下，再加上 Databases 和 Database language 的演進，使的大眾可以更方便、更有效率的收尋資料。

Ex: 以圖書館為例。現在到圖書館查一閱本書籍，只要在電腦系統中 key in 一些 keypoint 就可以找到相關書籍的資料，省時又方便。

(1)簡潔(compactness)
(2)迅速(speed)
(3)節省人力(less drudgery)
(4)即時性(currency)
(5)資料可以共用
