Abstract:	書本，乃是智慧的傳承，閱讀書籍可以使人獲得知識、增廣見聞，隨著近年科技的進步，書籍也成為今日數位化的主角。傳統的書籍以紙張為媒介，不但易損壞且保存不易，更會因為大量砍伐樹林而導致生態的破壞。在數位的世界裡，安全性總是一個關鍵的問題，數位的財產總是容易在網路中非法散佈、流傳，在書籍數位化的過程中，為了保護書籍的版權及作者的著作權，我們在開發時採用了數位版權管理(DRM)，以防止非法使用者惡意散佈非法的數位產權內容。在軟體工程的概念中，任何一套軟體都需要進行維護的動作，因此我們實作一套有效率的更新模組，以便於進行軟體的維護。在該模組中，我們採用了二元檔案分歧法(Binary-diff Method)，以提供更有效率的軟體更新方式。最後，開發電子書籍軟體，所需要紀錄的資料甚多，資料庫的設計也顯得格外重要，本論文闡述了電子書軟體的資料庫設計理念，期許在未來書籍資料量劇增之時，本資料庫仍能提供最有效率的資料存取。Digitizing of analog media, such as music, appliances, or TV, becomes an important trend for our life. According to observing, music now has become a clearly media with high resolution from an old LP disc, and we’ve advocated the digital TV which with high clear scene such as 1080p. These are good instances of digitizing. Books are knowledge. We can not only understand knowledge which ancient left us, but increase our visibility and cultivate our mind through reading. Traditionally, books are made of papers which are easily destroyed, and hard to preserve. Digitizing of books now becomes an important trend in the coming years. A digital e-book device can easily take thousands of books once, and besides avoid deforestation to protect our environment. Security is a critical problem in digital world. Malicious user can illegally disseminate legal files by internet easily. How to protect the copyright of e-books is the most important issue in developing e-book software. We involve the Digital Right Management (DRM) mechanism to protect literal properties, and prevent from disseminating illegal digital media. To follow the conception of software engineering, we develop an efficient updating module by exploiting binary diff mechanism which can generate a difference-patched file. We use the patch to upgrade our software instead of replacing the whole binary files. It significantly increases updating speed. Finally, a good e-book client depends on a good database. In this thesis, we state the conceptual development of database design. We intended to provide an efficient and stable database in numbers of stress.
