商品描述
When using software products with graphical interfaces, we frequently focus so much on the interface that we forget about the general concepts that allow us to understand and use the software effectively. In particular, this book focuses on three areas:
- Database design. The book provides an enjoyable, informative
overview of database design that carefully shows you how to normalize tables
to eliminate redundancy without losing data.
- Queries. The book examines multi-table queries (i.e.,various
types of joins) and shows how to implement them indirectly by using the Access
interface or directly by using Access SQL.
- Programming. The book examines the VBA integrated development
environment (IDE). It then goes on to provide an excellent introduction to
Data Access Objects (DAO), ActiveX Data Objects (ADO), and ADO Extensions for
Data Definition and Security (ADOX). These sections serve as a handy
introduction and primer for basic database operations,such as modifying a
table under program control, dynamically adding and deleting a record, and
repositioning a record pointer. The concluding chapter focuses on common
programming problems, such as computing running sums and comparing two sets.
Unlike other Access books that take the long, detailed approach to
every topic of concern to Access programmers, Access Database Design &
>Programming instead focuses on the core concepts, enabling
programmers to develop solid, effective database applications. This book also
serves as a ?second course? in Access that provides a relatively experienced
Access user who is new to programming with the frequently overlooked techniques
necessary to develop successfully in the Microsoft Access environment.
Anyone interested in learning Access in depth, rather than just scraping
the surface, will enjoy and benefit immensely from reading this book

商品描述(中文翻譯)
《Access 資料庫設計與程式設計》帶您深入了解 Access 介面的細節,專注於 Access 高級使用者或開發人員創建有效資料庫應用程式所需的一般知識。當使用具有圖形介面的軟體產品時,我們經常過於專注於介面,以至於忘記了使我們能夠有效理解和使用軟體的一般概念。特別是,本書專注於三個領域:
- 資料庫設計。本書提供了一個愉快且具資訊性的資料庫設計概述,仔細展示了如何對表進行正規化,以消除冗餘而不損失數據。
- 查詢。本書探討了多表查詢(即各種類型的聯接),並展示了如何通過使用 Access 介面間接實現它們,或通過使用 Access SQL 直接實現。
- 程式設計。本書探討了 VBA 整合開發環境(IDE)。接著提供了對資料存取物件(Data Access Objects, DAO)、ActiveX 資料物件(ActiveX Data Objects, ADO)以及 ADO 擴展資料定義與安全性(ADOX)的優秀介紹。這些部分作為基本資料庫操作的便捷入門,例如在程式控制下修改表、動態新增和刪除記錄,以及重新定位記錄指標。最後一章專注於常見的程式設計問題,例如計算累計和比較兩組數據。
與其他 Access 書籍對 Access 程式設計師關心的每個主題採取詳細的長篇方法不同,《Access 資料庫設計與程式設計》則專注於核心概念,使程式設計師能夠開發穩固且有效的資料庫應用程式。本書也作為 Access 的「第二課程」,為對程式設計新手的相對經驗豐富的 Access 使用者提供了在 Microsoft Access 環境中成功開發所需的經常被忽視的技術。
任何希望深入學習 Access 而不僅僅是淺嘗輒止的人,都會從閱讀本書中獲得極大的樂趣和益處。
