商品描述
Java and databases make a powerful combination. Getting the two sides to work together, however, takes some effort--largely because Java deals in objects while most databases do not.
This book describes the standard Java interfaces that make portable object-oriented access to relational databases possible and offers a robust model for writing applications that are easy to maintain. It introduces the JDBC and RMI packages and uses them to develop three-tier applications (applications divided into a user interface, an object-oriented logic component, and an information store).
The book begins with a quick overview of SQL for developers who may be asked to handle a database for the first time. It then explains how to issue database queries and updates through SQL and JDBC. It also covers the use of stored procedures and other measures to improve efficiency, where these are available.
But the book's key contribution is a set of patterns that let developers isolate critical tasks like object creation, information storage and retrieval, and the committing or aborting of transactions.
The second edition includes more basics of JDBC and SQL, with more examples, and a deeper discussion about the architecture of a robust, maintainable database application. The second edition also explains the relationship between JDBC and Enterprise JavaBeans.

商品描述(中文翻譯)
Java 與資料庫的結合是一個強大的組合。然而,讓這兩者協同工作需要一些努力,主要是因為 Java 處理的是物件,而大多數資料庫則不是。
本書描述了標準的 Java 介面,使得對關聯資料庫的可攜式物件導向存取成為可能,並提供了一個穩健的模型來編寫易於維護的應用程式。它介紹了 JDBC 和 RMI 套件,並利用它們來開發三層應用程式(將應用程式分為使用者介面、物件導向邏輯元件和資訊儲存)。
本書首先為可能第一次處理資料庫的開發人員提供 SQL 的快速概述。接著解釋如何通過 SQL 和 JDBC 發出資料庫查詢和更新。它還涵蓋了使用儲存過程和其他提高效率的措施(如果可用)。
但本書的關鍵貢獻是一組模式,讓開發人員能夠隔離關鍵任務,如物件創建、資訊儲存和檢索,以及交易的提交或中止。
第二版包含了更多 JDBC 和 SQL 的基礎知識,提供了更多範例,並對穩健、可維護的資料庫應用程式架構進行了更深入的討論。第二版還解釋了 JDBC 與 Enterprise JavaBeans 之間的關係。
