商品描述

 

The aim of this book is to teach cross-platform database programming to Delphi 6 or Kylix programmers. The book will assume the reader has a basic understanding of databases, such as what tables, rows, columns, fields, indexes, etc. are. It will also assume the reader has a working knowledge of Delphi and/or Kylix.

A thorough investigation of cross-platform database development using dbExpress will follow the introduction. Eric will cover topics ranging from setting up a database connection to single- and multi-tiered database applications. Along the way, he will present code snippets and small sample applications to illustrate the points being made. Also, a complete database application will be presented which will compile and run under either Delphi or Kylix, and will contain such discussed features as disconnected datasets.

商品描述(中文翻譯)

本書的目標是教授跨平台的資料庫程式設計給Delphi 6或Kylix程式設計師。本書假設讀者對資料庫有基本的了解，例如表格、列、欄位、索引等。同時也假設讀者對Delphi和/或Kylix有一定的工作知識。

本書將在介紹後進行對使用dbExpress進行跨平台資料庫開發的深入探討。Eric將涵蓋從建立資料庫連接到單層和多層資料庫應用程式的主題。在此過程中，他將提供程式碼片段和小型示範應用程式來說明所講述的重點。此外，將提供一個完整的資料庫應用程式，該應用程式可以在Delphi或Kylix下編譯和運行，並包含討論的功能，如斷開的資料集。
