《pb9.0软件开发项目实践》配套光盘
PB9.0，全称PowerBuilder 9.0，是一款由Sybase公司开发的面向对象的可视化编程工具，主要用于数据库应用程序的开发。本资源“《pb9.0软件开发项目实践》配套光盘”提供了丰富的学习材料，对于想要深入理解和掌握PB9.0的开发者来说，是一份极其宝贵的资料。
在PB9.0中，用户界面(UI)的设计是通过数据窗口(DataWindow)来实现的，这是一种强大的数据展示和编辑组件。数据窗口可以动态地连接到各种数据库，支持多种数据库访问方式，如ODBC、OLE DB等，使得数据操作变得简单直观。通过数据窗口，开发者可以轻松创建报表、表格和图形，实现数据的增删改查操作。
此外，PB9.0引入了对象导向编程（OOP）的概念，允许开发者创建自定义的函数、类和对象，增强了代码的可重用性和可维护性。它还支持事件驱动编程，使得程序能对用户的交互做出即时响应。PB9.0的脚本语言PBL（PowerScript）结合了C语言和Basic的特点，易学易用，是编写业务逻辑的关键工具。
在实际项目开发中，PB9.0的Workshop提供了完整的开发环境，包括设计器、编译器、调试器等，帮助开发者高效地进行应用构建。其应用程序服务器（PAS，PowerApp Server）则支持多用户分布式应用，使得PB9.0不仅适合桌面应用，也能胜任企业级的Web应用。
“pb项目实例”和“pb实例”标签表明，这个配套光盘可能包含了多个实际项目的源码和案例分析，这些案例可能涵盖了各种业务场景，如库存管理、客户关系管理、财务系统等。通过这些实例，学习者可以了解PB9.0在实际开发中的具体应用，学习如何设计架构、组织代码、优化性能，以及处理并发和安全性等问题。
在学习过程中，开发者可以逐一研究这些项目，理解它们的数据模型、业务逻辑和UI设计，对比自己的理解与实际应用，提升技能。同时，实例中的错误处理和异常处理机制也是值得学习的部分，它们能帮助开发者提高代码的健壮性。
“《pb9.0软件开发项目实践》配套光盘”是一套全面的学习资源，涵盖了PB9.0的基础知识、高级特性以及实战经验。无论是初学者还是有一定基础的开发者，都能从中受益，提升自己的PB9.0开发能力。通过深入学习和实践，你将能够利用PB9.0的强大功能，开发出高效、稳定且用户体验良好的数据库应用。
