基于Derby数据库技术的在线售书系统的实现 摘 要 随着电子计算机以及网络技术的飞速发展，国内外许多企业都在Internet上建立了自己的网站，为客户提供现代化的信息服务手段。网站已经成为一个企业数字化、网络化水平的重要体现。与此同时兴起的网上购物系统，在更广阔的范围上拉近了企业与客户的距离，不但节省了企业成本，提高了效率，而且也为用户节约了时间，是未来商务发展的趋势。但是在国内，网上购物还处于起步阶段。 Derby是完全用Java语言编写和实现的、占用资源少、基于标准的关系数据库管理系统。Derby可以完全地嵌入到任何用Java开发的解决方案中，允许静默安装和使用单一管理作用域。与在单独的进程中运行的其他数据库管理器不同，嵌入式 Derby与应用程序在同一 Java 虚拟机中运行。这极大地减少了数据库的开销。而且它还支持复杂 SQL事务，不会破坏数据一致性。 本文将以一个用Derby数据库支持的在线图书购买系统的开发过程，来展示如何将Derby与Tomcat进行集成、如何在Web解决方案中应用Derby以及如何快速部署Web解决方案。 【关键词】网上购物 Derby JSP Web解决方案 Abstract With the rapid development of the computer and web technology, many enterprises all over the world began to build their own web site on Internet to provide modern information services for their client. Web site is becoming a symbol of an enterprise advancing into digitizing and networking. Springing up at the same time with the enterprise web site, the online shopping system drew the distance between the enterprise and the client more closely. Not only did it save the enterprise cost and increase the enterprise efficiency， it also saved many time for clients. So online shopping is trend for future business affairs. But in china, online shopping is a new-arising phenomenon and it’s not very well-rounded. Derby，which is written and implemented completely in the Java programming language，is a small-footprint and standards-based relational database manager. It can be tightly embedded into any java based solution, enabling a silent install and a single administration scope. Unlike other database managers or relational database managers which run in a separate process, embedded derby could run in the same Java Virtual Machine as your application. This significantly reduces database overhead. Yet it ensures data integrity and provides sophisticated transaction support. This thesis will give a description of developing online book sale store to reveal how to integrate Tomcat and Derby、how to apply Derby and JSP in Web solution
