The DHCP Integrated Imaging System provides users with integrated patient data including text, image and graphics data. This system has been transferred from its original two screen DOS-based MUMPS platform to an X window workstation and a Microsoft Windows-based workstation. There are differences between these various platforms that impact on software design and on software development strategy. Data structures and conventions were used to isolate hardware, operating system, imaging software, and user-interface differences between platforms in the implementation of functionality for text and image display and interaction. The use of an object-oriented approach greatly increased system portability.
DHCP集成成像系统为用户提供包括文本、图像和图形数据在内的集成患者数据。该系统已从其最初基于双屏幕DOS的MUMPS平台转移到X窗口工作站和基于Microsoft Windows的工作站。这些不同平台之间存在差异，会影响软件设计和软件开发策略。在实现文本和图像显示及交互功能时，使用数据结构和约定来隔离不同平台之间的硬件、操作系统、成像软件和用户界面差异。采用面向对象的方法极大地提高了系统的可移植性。
