二十世紀后半葉，以電子計算機為代表的現代科學獲得了突飛猛進的發展并迅速和人們的日常生活結合在一起。計算機技術的發展和進步也使電子語言詞典的誕生成為可能。雖然只有十來年的歷史，電子詞典卻已經迅速發展壯大，成為詞典家族中具有旺盛生命力的一員。盡管目前它尚不足以取代傳統詞典，但在英語學習和教學中，由于它實用、快捷、準確、經濟等特點，已經成為傳統英漢詞典的有力競爭者，并對傳統的詞典提出了挑戰。
本文將要介紹的軟件就是一個多功能學單詞軟件，主要介紹了這個軟件制作環境，制作流程，對數據庫的操作以及它的使用方法。用戶可以根據自己的需要去查詢單詞，添加單詞，刪除單詞，編輯單詞等。另外，它還給單詞學習者們提供了一個背單詞的好方法。每一個用戶都可以通過創建一個用戶名來背誦單詞，隨時查看自己的歷史記錄，以便確定自己的背誦進度。本文從軟件工程的角度進行了詳細的闡述。該系統的開發工具是powerbuilder 9.0，使用的數據庫為Adapt Server Anywhere 。
